Split and tie notes of 'compound' durations

[csterritt]

First, thanks very much for doing Scribe! It's fantastic, and just what I need for a personal project.

From the "Dolphin Dance" demonstration file at bar 26:

There's a ledger line, and a flat symbol, and the tail for the note, but no note. There appears to be a similar issue in bar 13.

This is on both Safari 17.4.1 and Brave 1.65.126 on a Mac running OS Sonoma 14.4.1.

Scribe is not currently dividing up notes of certain lengths. This IS a note, it should be there, but because it is 3.5 beats long it should be divided into two heads, tied together, one 1/8th head tied to one dotted minim head.

Changing the issure title to reflect this.
