2021-03-17RP2040: Only bitbang 0-byte writesPhil Howard
The I2C.c for RP2040 included a special case for writes <=2 bytes to match the MicroPython implementation, however RP2040 does support 1 and 2 byte reads, with only 0 bytes being the exception. Signed-off-by: Philip Howard <phil@pimoroni.com>

2021-03-10raspberrypi: RTC: Ensure a time is setJeff Epler
Until a time is set, the RTC is not running, and rtc_get_datetime() returns false without assigning to the out-parameter. In CircuitPython, this would manifest as arbitrary values being returned, since uninitialized storage on the stack was being converted into a timestamp.

2021-03-05WIPrp2040: Implement IncrementalEncoderJeff Epler
Any two consecutive pins can be used for an IncrementalEncoder Testing performed: Put a synthesized (few hundred counts per second) quadrature signal into GP2/3 and read the encoder out. Performed filesystem operations at the same time to stress test it. The reasons for not using common_hal_rp2pio_statemachine_readinto are commented on.

2021-03-04rp2pio: Add pins_are_sequentialJeff Epler
This can be used where the standard API calls for a list of pins, to check that they satisfy the requirements of the rp2pio state machine, e.g., ```python def __init__(self, pin_a, pin_b): if not rp2pio.pins_are_sequential([pin_a, pin_b]): raise ValueError("Pins must be sequential") ```
2021-03-04StateMachine: Add pull up/down for inputsJeff Epler
2021-03-04StateMachine: Add in_available propertyJeff Epler
I named the property `in_available` because it is similar to pyserial. However, it indicates the number of words in the fifo, not the number of bytes.
