Subject: atmel-samd: Add APA102 support and flash more advanced status.

The new sequence is as follows:
* Solid blue during the boot/settings script.
* Solid green during the main/code script.
* After main while waiting to enter repl or reset:
  * Fading green once main is done successfully.
  * On error produce a series of flashes:
    * Long flash color of script.
    * Long flash color of error:
      * Green = IndentationError
      * Cyan = SyntaxError
      * White = NameError
      * Orange = OSError
      * Yellow = Other error
    * Line number of the exception by digit. Number of flashes represents value.
      * Thousands = White
      * Hundreds = Blue
      * Tens = Yellow
      * Ones = Cyan
    * Off for a period and then repeats.

At any point a write to the flash storage will flicker red.

Fixes #63
