add these... really old and dunno if any good.
remove bufid from SampleStuff - just use the name from the synth.
changes to key map algo - allow multiple 'soundbanks' and then have multiple key layouts that use those soundbanks.

also, load all samples at program start instead of reloading samples from disk each time.
go from WavSet to NoteWavSet and KeyWavSet, where KeyWavSet is a direct mapping
from keys to sounds, no scales or transposing or etc.
add support for these to scoscandir.
remove a bunch of dead code comments.
