3bd4c24ea8 Modified debugger so the input is in the frontend
The debug loop that reads a command and does something is part of the
frontend's main loop, so that it can potentially update, even though
it doesn't actually work for minifb because the command input is a
blocking call.  It's also not implemented in the pixels frontend.
At some point I'll make a web frontend.

708e7706f3 Fixed many of the undocumented tests
Now it's up to 99% tests passing, 15362 are still failing, but many
of those are the unimplemented IN/OUT instructions, which the Genesis
doesn't seem to use

Special thanks to raddad772 https://github.com/raddad772

Also added some fixes to the Z80 for panicking math operations, but
it still won't complete due to an unimplemented instruction

527f65c69b Refactored audio to use ClockedQueue
It now actually checks the clock and tries to mix the audio in sync
relative to the clock, but the cpal output doesn't yet try to sync
to the StreamInstant time.  Sound seems a lot better on chrome in
wasm, but and kind of better on firefox despite frame skipping not
being supported yet, but it's way slower for some reason (12fps)

transistor
71cd47466b Getting closer on the ym2612 implementation
It now sort of sounds like the main instrument, but the drums and bass
aren't there, and I'm not sure why.  I'm pretty sure the envelope and
phase generators are working, and there is feedback although it might
not be correct.  There's no LFO but that isn't used by Sonic 1 from
the register writes at least.

transistor
03561f1427 Fixed a bug in the frequency setting code for ym2612
It was previously only updating the frequency if the A0 registers
were written last, but now it works the way the rate code does, using
the cached register values to set the frequency whenever a register
is written to.  It also stores the fnumber and block in the operator
which I guess would be needed eventually if I want to save and restore
state.

transistor
31faf70d97 Fixed many bugs in ym2612, and switched to square wave
- The envelope generator wasn't working as it should have, minor issues
  with the limits and whether to use 10-bit or 12-bit values (more to come)
- fixed issues with sustain level where it was always set to 0
- fixed release rate and levels to make them 5-bit and 10-bit numbers
  respectively, so they match the others
- switched from SineWave to SquareWave and this alone made it go from
  terrible and muddy to not that far off.  I probably need to completely
  change the output

- also included an attempt at removing HostData, still needed for an
  interrupt that is triggered by user input
