d39c85e3f5 nRF: Change analog reference to VCC(/4)
@ladyada says:
"having this be adjustable (reference) would be ideal cause you can get
absolute voltages but for now, VCC/4 + 4x matches every other chip :)"

... and indeed doing it this way happens to give a much more steady
reading when using a VCC-referenced resistance, and so many of the simple
things you'd wire up are actually VCC-referenced anyway.

c56186da8c nRF: Change analog reference voltage
Datasheet reading explains one reason why readings might have been 10% low.

7b9dfc9952 nrf: i2s: tune audio buffering
.. based on some tasks I found that caused stuttering:

 # Test SD and printing
 while True: os.listdir('.')

 # Test bulk I/O
 while True: len(open('somefile.wav', 'rb').read())

Each of these tasks *WAS* worse and I am improving them in a separate
PR by adding RUN_BACKGROUND_TASKS to them.

f38ee42874 nrf: Add i2s audio output
Testing performed: I used a Particle Xenon with a HDA1334 I2S DAC.
I played a variety of mono 16-bit samples at 11025 and 22050Hz nominal
bit rates.  With this setup, all the 11025Hz samples sound good.
I tested play, pause,  and loop functionality.

During some runs with 22050Hz samples, there were glitches.  However,
these may have only occurred during runs where I had set breakpoints
and watchpoints in gdb.

I also tested with a MAX98357A I2S amplifier.  On this device, everything
sounded "scratchy".  I was powering it from 5V and the 5V rail seemed
steady, so I don't have an explanation for this.  However, I haven't
tried it with a SAMD board.
