midi: add generator
...
This adds both a midi generator and a midi type 1 simulator.
While I would have preferred to use an existing tool for this, I found
that timidity++ does not emit pitch wheel events correctly, and I
don't know of another widely-distributed tool that does midi-to-midi
format conversion.
The c++ and python versions were co-developed. I wrote one to test the
other. There is more cleanup to do, but `roundtrip.cpp` produces a
valid type 0 midi file given a type 1 or type 0 midi file as input.

midi: slow down TIMA interval
...
This also fixes the ordering of slot reference and slot_ix
deinitialization when turning off notes.

midi: add basic polyphony
...
Timing is still broken/inconsistent between emulators and I don't yet
understand why.

midi: play c major scale
...
TIMA occurs at half the speed predicted in the SCSP manual in
mednafen, but at the correct speed in Kronos. I don't know which is
correct.

m68k: rationalize frame math
...
On real hardware and mednafen, there is still a playback "gap". I
don't yet understand why.

m68k: add new "interrupt" example

I don't completely understand how the scsp timers work; "8192" is a
magic number I came up with by experimentation.
