Full extraction with ms3 v2.4.1, including chords facet; added pre-commit hook (workflow v4.3)

Added chords facet

Not to be confounded with labels or chord annotations, a chord is a notational unit in which all included notes are part of the same notational layer and have the same onset and duration. Every chord has a chord_id and every note is part of a chord. These tables are used to convey score information that is not attached to a particular note, such as lyrics, staff text, dynamics and other markup. More information on the columns can be found in the documentation of the ms3 parser.

Added pre-commit hook

The new iteration of the DCML annotation workflow moves the automatic validation of scores and annotations from GitHub actions to the local user. Whenever you are planning to commit changes to the annotation labels, you may want to install the pre-commit package to then run pre-commit install in your local clone. From this moment on, each time you try to commit changes to one or several MuseScore files, the hook will run ms3 review on them and will reject the commit if warnings are detected. If no warnings are detected, the commit will be enriched with all updates to the repo's TSV files that reflect the changes you've made to the scores.
