Provide actual source code

[introt]

Currently, the project provides .mid files. While the format is standardized, the Standard MIDI File more of an end-product than an instance of source code.

To realize the dream of a true Free and Open Source Software Chord Pack, I suggest we use MIDIUtil, a Python program released under the MIT license, to generate all the possible chords programmatically, and publish the generator code here, and the resulting artifacts via Releases - we could even set up a GitHub Actions workflow to compile the chords automatically.

...yes, I know there's prior art, but this sounds like a fun problem to solve (pun intended).

Edit: ldrolez/free-midi-chords is a better example and a true realization of the FOSS Chord Pack with 7k+ files, also available under MIT. Well done y'all!
