music-notation

Task description
This is a task that does not need to be implemented for 4.0. However, if a community member is interested, these are the fonts that it would make the most sense for us to include:

• Finale Maestro (& Finale Maestro Text)
• Finale Broadway (& Finale Broadway Text

You can get them here: https://makemusic.zendesk.com/hc/en-us/articles/1500013053461-MakeMusic-Fonts

As reported here alphaTab does not support reading the individual frets and strings from the MusicXML harmony definition. We can use the information from the frame element to fill up all strings and frets of the chord accordingly:

[demo.xml.txt](https://github.com/CoderL

See attached image - if a dynamic and player change are at the same location the text can overlap

Now that we are disabling .trimValueWhitespaces from our decoder, it may make sense to create an XMLDecoder subclass MusicXMLDecoder.

This way we can use MusicXMLDecoder when testing atomic units, so we know we are working with the same thing when decoding a whole MusicXML object.

This will also allow us to wipe XMLCoder from testing, which has seemed slightly out of place.
