Scott Shawcroft 4a4f29b8f9 atmel-samd: Rework status LED implementation 
* Track status pin use by user code separately so it can take over the pins and then give them back.
* Switch to hardware SPI for APA102 on Gemma and Trinket.
* Merge microcontroller/types.h into microcontroller/Pin.h to better match approach going forwards.

Scott Shawcroft 781633c716 Fix up Analog classes: unify them at 16 bits and adds reference_voltage member 
to make for easy conversion. Fixes #14.

Scott Shawcroft 0ae344841f atmel-samd & esp8266: Make sure pins are not already in use. 
This prevents corrupting previous functional objects by stealing their pins
out from under them. It prevents this by ensuring that pins are in default
state before claiming them. It also verifies pins are released correctly and
reset on soft reset.

Fixes #4, instantiating a second class will fail.
Fixes #29, pins are now reset too.
