DONE: ql-ppt1sut2su1 is in the ms verse (different from the modern verse), but does not exist in NABC yet. Add it (not done), or use synthetic NABC instead of the ms's verse neumes (done), and fix the square notes accordingly (done).

Used the more common ql-ppt1su1sut2 in the synthetic verse. This unique feature of H's verse is probably a copy error.
