a183425e00 ports/nrf: Implement audioio.AudioOut using PWM 
This implements AudioOut, with known caveats:
 * pause/resume are not yet implemented (this is just a bug)
 * at best, the sample fidelity is 8 bits (this is a hardware limitation)

Testing performed:

My test system is a Particle Xenon with a PAM8302 op-amp
https://www.adafruit.com/product/2130 and 8-ohm speaker.  There's no
analog filtering between the Xenon's PWM pin and the "A+" input of
the amplifier; the "A-" pin is disconnected.  It is powered from
VUSB.

I used pin D4, which is *NOT* listed as a low-speed-only pin, but
the code does NOT switch the pin to high drive.  This is related to
an open issue for general inability to set drive level for pins
being used by a "special function" on nrf:
https://github.com/adafruit/circuitpython/issues/1270

Nothing about the code I've written should limit the usable pins.

All samples I played were 16-bit, generally monophonic at 11025Hz
and 22050Hz from the Debian LibreOffice package.

6b44e40ee8 audiocore: Factor from audioio 
When nrf pwm audio is introduced, it will be called `audiopwmio`.  To
enable code sharing with the existing (dac-based) `audioio`, factor
the sample and mixer types to `audiocore`.

INCOMPATIBLE CHANGE: Now, `Mixer`, `RawSample` and `WaveFile` must
be imported from `audiocore`, not `audioio`.

Add support for grayscale displays that are < 8 bit depth. 
This also improves Palette so it stores the original RGB888 colors.

Lastly, it adds I2CDisplay as a display bus to talk over I2C. Particularly
useful for the SSD1306.

Fixes #1828. Fixes #1956
