Rearranged TaleaRhythmMaker initializer arguments again.

OLD:

    ...
    extra_counts_per_division=None,
    split_divisions_every=None,
    ...

NEW:

    ...
    split_divisions_every=None,
    extra_counts_per_division=None,
    ...

Explanation: conceptually it's very important to understand that any division
splitting happens before any adding of extra counts.

This seems to be the right use for (nonalphabetized) ordering of initializer
input arguments.
