61698eb5d8 AnalogOut / AudioOut: Copy settings from Arduino 
Make changes in asf4_conf even though I think in these cases the
"peripherals" submodule is running the show.

Arduino clocks the DAC at 12MHz but uses the CCTRL setting for
clocking < 1.2MHz (100kSPS).

A fresh clock (6) is allocated for the new 12MHz clock.  This matches
the Arduino value, though not the GCLK index.

Modify other settings to more closely resemble Arduino.

In AudioOut, actually clock the waveform data from the timer we set up
for this purpose.

This gives good waveforms when setting AnalogOut full-scale in a loop,
but the rise/fall of waveforms that come from AudioOut are still erratic.
Weirdly, if AudioOut limits its range even slightly (e.g., to 1000..64000)
then the erratic

Note that this will require https://github.com/adafruit/samd-peripherals/pull/26
to be accepted for the submodule update here to work.

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.
