DMA-based ADC input (microphone, analog sensor) (#1101 )

Mimics the I2S/PWMAudio/Stream interface for ease of use.

* Fix non-32b DMA size transfer calculation in ABM
* Rename wasHolding to isHolding in the I2S/PWM
  It is the **current** number of bits left, not the past number.
* Add commented microphone example
* Add docs

Allow on-the-fly changes to PWMAudio when possible (#1098 )

Also fix crash on PWMAudio::end()

Add stereo support, docs for PWM playback (#1084 )

Limited to consecutive pins (i.e. GPIOs on the same PWM slice).
"For free" with PWM since no add'l DMA, buffers, or IRQs are needed.
