fix(StringNumbersClassical): write as roman numerals, offset positioning, etc (#957, #949)

squash merge PR #957

closes #949

* Remove restriction displaying string number only on top chord note

Resolves https://github.com/opensheetmusicdisplay/opensheetmusicdisplay/issues/949

* Add Brahms example demonstrating string numbers on chords

* Implement more advanced logic for determining string number position

* Render string numbers as Roman Numerals on the right of notes

* Implement collision logic for modifiers on sides of notes with chords

* Add test for string number collisions

* Generalize offset calculation to all voices with simultaneous notes

* Improve control flow in modifier offset calculation

* fix reviewed issues in #957 [sschmidTU]

* Move string numbers to above position for single notes
