Fix errors in ia6cho charts

The official fumen had some issues where a note ended up in the wrong measure:

- Expected: pos 0.0 on the next measure
- Actual: pos 645 on the prev measure (impossible pos)

They're the same pos, but only pos 0.0 is possible to express in TJA charts, so the fumens themselves had to be updated.

Also, the TJA chart had errors, too:

- The BPMs/SCROLLs in the BPMCHANGE section were incorrect
- Some drumrolls were too short

Fixing these errors caused the failing test to pass.
