Split up nativeio.0.9.4

This was done to allow greatly granularity when deciding what functionality
is built into each board's build. For example, this way pulseio can be
omitted to allow for something else such as touchio.

-//| ------------------------------------------
-//|
-//| .. class:: I2C(scl, sda, \*, frequency=400000)
-//|
-//|   I2C is a two-wire protocol for communicating between devices.  At the
-//|   physical level it consists of 2 wires: SCL and SDA, the clock and data
-//|   lines respectively.
-//|
-//|   .. seealso:: Using this class directly requires careful lock management.
-//|       Instead, use :class:`~adafruit_bus_device.i2c_device.I2CDevice` to
-//|       manage locks.
-//|
-//|   .. seealso:: Using this class to directly read registers requires manual
-//|       bit unpacking. Instead, use an existing driver or make one with
-//|       :ref:`Register <register-module-reference>` data descriptors.
-//|
-//|   :param ~microcontroller.Pin scl: The clock pin
-//|   :param ~microcontroller.Pin sda: The data pin

-//| :class:`PWMOut` -- Output a Pulse Width Modulated signal
-//| ========================================================
-//|
-//| PWMOut can be used to output a PWM signal on a given pin.
-//|
-//| .. class:: PWMOut(pin, \*, duty_cycle=0, frequency=500, variable_frequency=False)
-//|
-//|   Create a PWM object associated with the given pin. This allows you to
-//|   write PWM signals out on the given pin. Frequency is fixed after init
-//|   unless ``variable_frequency`` is True.
-//|
-//|   .. note:: When ``variable_frequency`` is True, further PWM outputs may be
-//|     limited because it may take more internal resources to be flexible. So,
-//|     when outputting both fixed and flexible frequency signals construct the
-//|     fixed outputs first.
-//|
-//|   :param ~microcontroller.Pin pin: The pin to output to
-//|   :param int duty: The fraction of each pulse which is high. 16-bit
-//|   :param int frequency: The target frequency in Hertz (32-bit)
-//|   :param bool variable_frequency: True if the frequency will change over time
-//|
-//|   Simple LED fade::
-//|
-//|     import nativeio
-//|     import board
-//|
-//|     with nativeio.PWMOut(board.D13) as pwm:     # output on D13
-//|       pwm.duty_cycle = 2 ** 15                  # Cycles the pin with 50% duty cycle (half of 2 ** 16) at the default 500hz
-//|
-//|   PWM at specific frequency (servos and motors)::
-//|
-//|     import nativeio
-//|     import board
-//|
-//|     with nativeio.PWMOut(board.D13, frequency=50) as pwm:
-//|       pwm.duty_cycle = 2 ** 15                  # Cycles the pin with 50% duty cycle (half of 2 ** 16) at 50hz
-//|
-//|   Variable frequency (usually tones)::
-//|
-//|     import nativeio
-//|     import board
-//|     import time
-//|
-//|     with nativeio.PWMOut(board.D13, duty_cycle=2 ** 15, frequency=440, variable_frequency=True) as pwm:

-//| :class:`PulseIn` -- Read a series of pulse durations
-//| ========================================================
-//|
-//| PulseIn is used to measure a series of active and idle pulses. This is
-//| commonly used in infrared receivers and low cost temperature sensors (DHT).
-//| The pulsed signal consists of timed active and idle periods. Unlike PWM,
-//| there is no set duration for active and idle pairs.
-//|
-//| .. class:: PulseIn(pin, maxlen=2, \*, idle_state=False)
-//|
-//|   Create a PulseIn object associated with the given pin. The object acts as
-//|   a read-only sequence of pulse lengths with a given max length. When it is
-//|   active, new pulse lengths are added to the end of the list. When there is
-//|   no more room (len() == `maxlen`) the oldest pulse length is removed to
-//|   make room.
-//|
-//|   :param ~microcontroller.Pin pin: Pin to read pulses from.
-//|   :param int maxlen: Maximum number of pulse durations to store at once
-//|   :param bool idle_state: Idle state of the pin. At start and after `resume`
-//|     the first recorded pulse will the opposite state from idle.
-//|
-//|   Read a short series of pulses::
-//|
-//|     import nativeio
-//|     import board
-//|
-//|     with nativeio.PulseIn(board.D7) as pulses:
-//|         # Wait for an active pulse
-//|         while len(pulses) == 0:
-//|             pass
-//|         # Pause while we do something with the pulses
-//|         pulses.pause()
-//|
-//|         # Print the pulses. pulses[0] is an active pulse unless the length
-//|         # reached max length and idle pulses are recorded.
-//|         print(pulses)
-//|
-//|         # Clear the rest
-//|         pulse_in.clear()
-//|
-//|         # Resume with an 80 microsecond active pulse
-//|         pulse_in.resume(80)

-//| .. currentmodule:: nativeio
-//|
-//| :class:`SPI` -- a 3-4 wire serial protocol
-//| -----------------------------------------------
-//|
-//| SPI is a serial protocol that has exclusive pins for data in and out of the
-//| master.  It is typically faster than :py:class:`~nativeio.I2C` because a
-//| separate pin is used to control the active slave rather than a transitted
-//| address. This class only manages three of the four SPI lines: `!clock`,
-//| `!MOSI`, `!MISO`. Its up to the client to manage the appropriate slave
-//| select line. (This is common because multiple slaves can share the `!clock`,
-//| `!MOSI` and `!MISO` lines and therefore the hardware.)
-//|
-//| .. class:: SPI(clock, MOSI=None, MISO=None)
-//|
-//|    Construct an SPI object on the given pins.
-//|
-//|   .. seealso:: Using this class directly requires careful lock management.
-//|       Instead, use :class:`~adafruit_bus_device.spi_device.SPIDevice` to
-//|       manage locks.
-//|
-//|   .. seealso:: Using this class to directly read registers requires manual
-//|       bit unpacking. Instead, use an existing driver or make one with
-//|       :ref:`Register <register-module-reference>` data descriptors.
-//|
-//|   :param ~microcontroller.Pin clock: the pin to use for the clock.
-//|   :param ~microcontroller.Pin MOSI: the Master Out Slave In pin.
-//|   :param ~microcontroller.Pin MISO: the Master In Slave Out pin.

-//| :mod:`nativeio` --- Hardware accelerated behavior
-//| =================================================
-//|
-//| .. module:: nativeio
-//|   :synopsis: Hardware accelerated behavior
-//|   :platform: SAMD21
-//|
-//| The `nativeio` module contains classes to provide access to IO typically
-//| accelerated by hardware on the onboard microcontroller. The classes are
-//| meant to align with commonly hardware accelerated IO and not necessarily
-//| match up with microcontroller structure (because it varies).
-//|
-//| When the microcontroller does not support the behavior in a hardware
-//| accelerated fashion it may internally use a bitbang routine. However, if
-//| hardware support is available on a subset of pins but not those provided,
-//| then a RuntimeError will be raised. Use the `bitbangio` module to explicitly
-//| bitbang a protocol on any general purpose pins.
-//|
-//| Libraries
-//|
-//| .. toctree::
-//|     :maxdepth: 3
-//|
-//|     AnalogIn
-//|     AnalogOut
-//|     DigitalInOut
-//|     I2C
-//|     OneWire
-//|     PulseIn
-//|     PulseOut
-//|     PWMOut
-//|     SPI
-//|     TouchIn
-//|     UART
-//|
-//| All libraries change hardware state and should be deinitialized when they
-//| are no longer needed. To do so, either call :py:meth:`!deinit` or use a
-//| context manager.
-//|
-//| For example::
-//|
-//|   import nativeio
-//|   from board import *
-//|
-//|   with nativeio.I2C(SCL, SDA) as i2c:
-//|     i2c.scan()
-//|
-//| This example will initialize the the device, run
-//| :py:meth:`~nativeio.I2C.scan` and then :py:meth:`~nativeio.I2C.deinit` the
-//| hardware.
-//|
-//| Here is blinky::
-//|
-//|   import nativeio
-//|   from board import *
-//|   import time
-//|
-//|   with nativeio.DigitalInOut(D13) as led:
-//|     led.switch_to_output()
-//|     while True:
-//|       led.value = True
-//|       time.sleep(0.1)
-//|       led.value = False
-//|       time.sleep(0.1)
-//|
