Support 11 cycle cadence using STA $BFFF,Y(=31). This slightly improves quality

WIP - refactor player generation to be a) deterministic b) use opcodes_6502 c) statically enumerate a minimal set of opcode sequences. Since we're giving up on using arbitrary opcode combinations this is much simpler, and maybe more correct.

Working version of encoder. This reproduces the clicking that happens from end-of-frame, so we will need a new strategy

Fixup player timings and opcode variants for 65c02 timings since JMP
...
(indirect) takes 5 cycles not 6! It should be possible to also
accommodate 6502 timings in a followup.
h/t to Scott Duensing who noticed that my sample audio sounded "a tad
slow", which turned out to be due to this 1-cycle difference (which
added up to almost an extra minute playback to an 8-minute song).
Add comments and tidy up the code a bit.
Flesh out README some more.
