Since Python 3.11, `FileLock` is thread-local by default, which causes
numerous issues with Rare because of numerous operations running in
`QThreads` and `QRunnables`. To work around it, add a monkey LGDLFS class
that uses a non-thread-local instance of `FileLock`. Since the monkey class
exists, implement a `unlock_installed` method for code clarity
* Add decorate `LegendaryCore.egl_sync` with `unlock_installed`
* Log that Rare's monkeys are in use
* Add function signature protocols based on `typing.Protocol`
