Notice about a subtree imported without --squash

[MysticILD]

Hello @vocoder712, I noticed #290 and #291 brought in ~2,600+ individual commits from OpenUtau because it was added without --squash.
I think it might be best to re-import it with git subtree add --squash (or squash it before merging dev into master) so the main branch history and contributor list don't get flooded.

Thanks for pointing this out so quickly! I’ve fixed the issue now —— the imported OpenUtau commit history has been cleaned up while keeping the current dev contents unchanged.

Future upstream syncs will also avoid bringing the full OpenUtau history into dev.

Thanks again for reminding me of this in time!
