- Rewrote arpeggio implementation to use note offset tables
- Implemented Fast Tracker II arpeggio bug (ticks count backwards from
  speed minus one, speeds greater than 15 result in note offsets reading
  from the vibrato table, which gets clamped to 2)
Merge branch 'master' of github.com:kode54/dumb
Apply delta to compressed samples regardless of creating tracker version
