synthio: lfo: bugfixes & improvements 
LFO waveforms are now linearly interpolated by default, but a new
property (interpolated=False) can disable this.

The 'once' logic was improved

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.

synthio: Fix release time of zero-sustain envelopes 
When there's no sustain, the release step needs to be calculated from
the attack level, not the sustain level. Otherwise, contrary to intent,
this leads to the actual release taking a loooonnngg time.

place it partially in both channels.

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

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: 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
