Cache configuration descriptor
...
We use it to open endpoints as they are used. Fetching the descriptor
as needed can cause issues with devices that we're expecting a control
packet while another transaction was ongoing. Specifically, a usb
thumb drive didn't expect a control transaction while doing a SCSI
transaction.
This PR also aborts transactions on timeout or ctrl-c interrupt. It
doesn't always recover though...

3. Fix submodule location for ulab to Jeff's copy.

synthio: Add Synthesizer.note_state
...
This enables the specific use case of checking whether a note's release
phase has ended, but is also potentially useful to implement a sort of
"voice stealing" algorithm in Python code, which can take account of
the note's envelope state as well as other factors specific to the
program.

synthio: reorganize the order of operations
...
Apply envelope & panning after biquad filtering.
This may fix the weird popping problem. It also reduces the number
of operations that are done "in stereo", so it could help performance.
It also fixes a previously unnoticed problem where a ring-modulated
waveform had 2x the amplitude of an un-modulated waveform.
The test differences look large but it's because some values got changed
in the LSB after the mathematical divisions were moved around.

synthio: improve release/press/change

Semi-incompatible name change: The method `release_then_press`
is now `change`. For now a compatibility alias is supported.
Everywhere a `NoteSequence` was accepted, a single note is now accepted.
So for instance, `synth.press(30)` can be written instead of requiring
``synth.press((30,))`. The same goes for `change.retrigger`, which
will accept a single LFO or a sequence.

Now the vibrato 'units' are 1.0 = one octave, 1/12 = one semitone,

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#
