- Only use the minimal player, quality is better and we don't often need more than 6 cycle gaps
...
- Generate 1-cycle EOF opcodes for now, but we'll need to tweak further.
- Generate both duty cycle orderings (a,b) and (b,a) since we anchor the EOF opcodes with a STA $C030 at the beginning
- Sort EOF by total length so it's clearer when looking at the usage profile which ones are needed

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.

Switch back to longest opcodes first, it is both smaller and slightly
better quality (~3%).
