feat(Chords): Elongate measures for chords (merge PR #928)

code mostly by @hartman42

* Add Test file for chord spacing

* update my chord test with a multirest

* fixed halfdim chords with the extra flat 5's

* Elongate measure for chords

* align chords to the bottom left

* Refactor width calculations for lyrics and chords.

* update demo files

* Add rule for chord overlap into next measure

* format changes based on existing code conventions

* pr #928 review: requested changes (chord spacing) - sschmidTU
