Awesome work! It would be super cool if this could somehow run as a WASM module. Was thinking I would then try to include it in Freetar [0], for example so it can be used to play the tablatures on a page like this: https://freetar.de/tab/joni-mitchell/a-case-of-you-chords-95...
TBH I have a lot of things to improve before thinking about this kind of interop.
But feel free to create an issue :)
