This should match most fumens. Some exceptional cases I've seen:
- [x] ~In official fumens, even-numbered clusters of 4 notes will
sometimes be ドドドド or カカカカ. Right now, my converter will always use ドドドドン
or カカカカッ, since I don't really understand the rules behind it.~ Fixed:
Now, all 16th notes and above in groups of 4 will no longer use the
don/kat ending character.
- [X] ~In official fumens, sometimes isolated notes will be grouped
together, but sometimes they will be treated as single clusters of 1.
Right now, my converter will always try to cluster isolated notes.~
Fixed: Only 4th/8th/16th/etc. notes will be clustered. Whole/half notes
will not be clustered.
- [x] ~Right now, my logic always treats big notes as their own cluster.
But, sometimes you get a cluster like `ddddD`, and right now my
converter treats this as (ドドドドン) + big DON instead of do-ko-do-ko-DON.~
Fixed: Now big notes are included in clusters.
- [x] ~For high-level Oni songs with complex groups of dense notes (e.g.
(12th/16th/24th) notes mixed with (16th/34th/32nd) notes), official
fumens seem to group them together even though they technically have
different timings. Right now, my converter will group the 32nd notes,
but treat the 16th notes as their own separate group.~ Fixed: Now
anything above an 8th note will be clustered together.
- [X] Songs with BPM gimmicks. e.g. the TJA has low base BPM, but then
everything is doubled/tripled except for one section. I can't remember
which songs have this? Something like RNG Cinderella?
- Maybe solved by

Fixes#41.
Now, instead of passing an entire TJACourse object, we pass the branch dict. This makes the function signature _much_ clearer, since it's easier to compare the before and after.
This PR adopts static type hints as per `mypy` recommendations. This
will hopefully clean up the code a little and squash a few type-related
bugs.
Additionally, this will hopefully open up the door to compiling the
project using `mypyc`, which may score us some performance gains without
needing to rewrite the project in an entirely new language.
