jepler 676f7aa808 os_listdir: This can be long-running, run background tasks 
While finding sources of clicks and buzzes in nrf i2sout, I identified
this site as one which could be long running.  Reproducer code was to
play a 22.05kHz sample and repeatedly print `os.listdir('')`

jepler 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.

jepler 8768896d6b audiomixer: Supply constants in a way "-Og" optimization expects 
These arguments are constrained to be compile-time constants, a fact
that gcc complains about under "-Og" optimization, but not in normal

jepler 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.
