Update annotations in CHAs and OPF

• Copy the CHAs/OPFs you want to update into a separate folder and edit the copies only.

• Update using CLAN/DataVyu or any other way you prefer.

• Go to a local clone of "annotated_cha" or "annotated_opf" repositories (you might need to create one first).

• Run "backup.py". Check the diff, commit, push. This will sync the CHAs/OPFs from "Seedlings/Subject_Files" to your local clone.

• Copy new CHAs/OPFs to the appropriate places in the repository (for OPFs, see "annotated_opfs/opfs_to_unpack/README.md"). Check the diff, commit, push.

• Run "restore.py". This will sync CHAs/OPFs from your local clone to "Seedlings/Subject_Files".

• Propagate the changes down the pipeline to seedlings-nouns.
