Extend NoteRhythmMaker with maximum_duration property to accommodate headless rhythms unambiguously

Observe the following:

maker = rhythmmakertools.NoteRhythmMaker() maker([(2, 4)]) [[Note("c'2")]]

This makes perfect sense.

But a problem arises when the resulting rhythms are used as the headless rhythm voice in a tablature staff. Why? Because headless half notes and headless quarter notes can not be distinguished.

The solution is allows for something like NoteRhythmMaker(maximum_duration=Duration(1, 4)) which will then generate c'4 ~ c'4 in place of c'2.

Done in 2.13.

Use fobidden_written_duration keyword.
