Add a new ChordSymbol module

[danigb]

Add a module to parse chord symbols. Will replace the actual Chord.tokenize function but implementing chord roots (aka slashed chords).

It should fix most of the issues of #155

Would it be nice to have a custom font for tonal js where musical signs get pasted correctly on all browsers? When making Sonid I ran into the issue that the flat/sharp (and others) signs had different spacing and sizes on different OSses.

After a bit of experimenting I found that using a custom font with svg glyphs and setting them in a span with css content solved the issue. It might nice to include a property which pastes names with musical signs inside all notes/chords/scales objects. Although, come to think of it, it would have to be multilanguage aswell...

Hello, Not sure how well it fits your use case but this lib can parse chord-symbols into intervals: https://github.com/no-chris/chord-symbol Let me know if any interest, I could assist with the integration

Hi Chris,

You library looks great! Congrats. Anyway, I think it's too complex for what I had in mind. Also some of functionality overlaps with tonal (interval to semitones, note names to name a few) so I think it's better to keep them separated.

Good work and thanks for sharing
