9eadda68b8 atmel-samd: Fix AudioOut buffer playback by supporting bytes_per_sample. 
Thanks to @ntoll for finding this bug!

c7efd2cae9 shared-bindings: Move enum-like classes out of DigitalInOut into digitalio. 
Also, rename Direction.IN to Direction.INPUT and Direction.OUT to Direction.OUTPUT.

This simplifies using them. Prior to the nativeio split this would have led to
clutter in the top-level namespace but having digitalio prevents this.

Fixes #152

3f5028c666 atmel-samd: Support wav file playback. Tested up to 16bit 22.1khz. Must be mono file! 
SD card support may work but likely needs buffer tuning. Its untested.

939c0045db Switch to a shared piece of code to compute start and length of a 
buffer from start, end and length. The old code miscomputed length
leading to writing and reading from memory past the end of the buffer.
Consolidating the code should make it easier to get right everywhere.

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.

f28f8ba568 Split up nativeio. 
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.

ff208d7677 Add low-level OneWire support class. 
This class focuses on the timing sensitive parts of the protocol.
Everything else will be done by Python code.

This also establishes that its OK to back a nativeio class with a
bitbang implementation when no hardware acceleration exists. When
it does, then bitbangio should be used to explicitly bitbang a
protocol.

"Express" builds with SPI flash crash the compiler for some reason so its
currently disabled for them.

710b5d8aff Two I2C fixes: 
1) Bus error will be thrown on read/write errors with errno set. (Read didn't used to fail at all.)
2) try_lock correctly returns boolean whether lock was grabbed.

9f6da7b2fe Add more PWMOut examples and rename the duty constructor argument 
to duty_cycle so that its consistent with the attribute.

e3f9ee839a Add frequency changing support to PWMOut. 
You can either set it once up front, or set variable_frequency on custruction to
indicate that the frequency must be able to change. This informs whether a timer
can be shared amongst pins.

This also adds persistent clock calibration on atmel-samd. Once the device has
synced its clock frequency over USB it will remember that config value until USB
is used again. This helps ensure the clock frequency is similar on and off USB.

Lastly, this also corrects time.sleep() when on USB by correcting the tick counter.
