synthio: Perform vibrato in pitch, not as frequency ratio 
Now the vibrato 'units' are 1.0 = one octave, 1/12 = one semitone,
1/1200 = one cent. Before, the units were somewhat arbitrary and were not
perceptually "symmetrical" around the base frequency.

For vibrato_depth = 1/12 and base frequency of 440,

before: pitch from 403.33 to 476.67Hz, not corresponding to any notes
after: pitch from 415.30 to 466.16Hz, corresponding to G# and A#

synthio: add onevo_to_hz, implement midi_to_hz in terms of it 
this has the side effect of making some notes more accurate, the new
frequency= value in the test is closer to the true midi frequency of
830.609...Hz.

synthio: fix per-note envelope & envelope modification 
.. and simplify the envelope advance logic by handling
'instant' values more intelligently.

synthio: make most Note constructor args kw-only 
for similar reasons as Envelope. The mandatory frequency argument can
still be given as a positional argument.

rp2040: fix audio glitch at soft-reload 
The internal flash cache wasn't being properly used, because
`write_blocks` unconditionally performed the flash write.

Fixing this so that the write's not done until `internal_flash_flush`
fixes the problem in my test program with i2sout & synthio.

as a future optimization, `flash_read_blocks` could learn to read out
of the cache, but that's probably not super important.

synthio: make sustain level relative to attack level 
and re-vamp overall envelope calculation again.

Now, if you set a low overall attack level like 0.2 this avoids the
"diminishing volume" effect when many notes sound at once. You need
simply choose a maximum attack level that is appropriate for the max
number of voices that will actually be played.

synthio: slow ramp overall envelope back up 
.. and account releasing notes at their sustain level until they're
done.

this ameliorates the effect where multiple releasing notes
don't seem to actually be releasing, but stay at a constant volume.

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 additional iMX RT support 
This adds a script to generate the peripherals files (except clock).

It adds support for the 1015, 1020, 1040, and 1050 EVKs.

Some work was started on 1176 but it isn't working. So, the board
def is in a separate branch.

Fixes #3521. Fixes #2477.
