fae6e29546 nrf: PWMAudioOut: deactivate PWM when deinitting self 
.. otherwise, when an AudioPWMOut object was deinitted without being
explicitly stop()ped, it would use up a slot in active_audio[]; the
5th iteration would create a non-working audio object which would just
buzz instead of playing the right thing.

Closes: #2203

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.

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.

This enables the highest level of debug symbols, and all optimizations
except lto that do NOT interfere with debugging, in the view of the gcc
maintainers.

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.
