feat: Add Note Head Shapes (Percussion) (#337)

feat(NoteHeadTypes): Add rendering of percussion heads (cross, diamond and triangle)
test(demo): add samples for drumset, note head shapes

Squashed commits:

* Reading and displaying note heads from XML (#327)

part of #325

* fix(noteHeadShapes): calculate filled from note length, draw circle-x, refactor

test(demo): add samples for drumset, note head shapes
refactor(noteHeadShapes): replace enum string values with static converter functions
leave note.noteHead undefined if the note head is normal to save performance
NoteHead.ts: add documentation

* lyricSpacing: remove misleading comments

* fix note head demo files

* noteHeadShapes: fix notehead not being undefined for normal note heads

* feat(NoteHeadShapes): add Slash note head
