synthio: implement a range compressor with hard knee
This really improves the loudness of the output with multiple notes
while being a nice simple algorithm to implement.

synthio: Add synthio.Note
This class allows much more expressive sound synthesis:
 * tremolo & vibrato
 * arbitrary frequency
 * different evelope & waveform per note
 * all properties dynamically settable from Python code

Add a manual test of synthio
this allows to test how the midi synthesizer is working, without access
to hardware. Run `micropython-coverage midi2wav.py` and it will create
`tune.wav` as an output.

Refactor dotenv module so that it can be tested on host
.. it needs to operate on a FILE* rather than FIL depending on
the build.

Note that this is comparing output to expected, not to cpython dotenv
package. Because run-tests.py starts the CPython interpreter with the
'-S' (skip site initialization) flag, pip-installed packages are
not available for import inside a test file. Instead, the exp
file is generated manually:
```
circuitpython/tests$ python3 circuitpython/dotenv_test.py > circuitpython/dotenv_test.py.exp
```

Unfortunately, the test fails on test e15:

Start of USB host API
This allows you to list and explore connected USB devices. It
only stubs out the methods to communicate to endpoints. That will
come in a follow up once TinyUSB has it. (It's in progress.)

Implement audiobusio and enhance PIO for it
This adds I2SOut and PDMIn support via PIO.

StateMachines can now:
 * read and read while writing
 * transfer in 1, 2 or 4 byte increments
 * init pins based on expected defaults automatically
 * be stopped and restarted
 * rxfifo can be cleared and rxstalls detected (good for tracking when
   the reading code isn't keeping up)
