adding more chord types

[dgy18787]

Could I add more chord types in the plugins like add9 or sus4?

Yes you can modify the structure here where you could add the intervals corresponding to the chords to be identified.

I have tried to add some new chords like [5,7] in this array but the plugins seems to be unable to mark it right (sus4). Should I also defined its name in chord_str array?
