Includes the following fixes:

- Don't cluster isolated 4th notes.
- Include big notes (大) in clusters (so that, for example, ddddD will be ド ド ド ド ドン(大) and not ド ド ド ドン ドン(大)
- Group mixed sets of dense notes together (12th, 16th, 18th, 24th, 32nd, 36th, etc.)
- Don't use "don" or "katsu" for dense groups of 4 (in other words, use only do/ka)

Includes fix for how isolated whole notes/half notes are grouped (will always be "don/katsu" and never "do/ka").

Includes fixes to how the positions of notes are calculated, and how notes are clustered, when BPMCHANGE commands are present.
