What's Changed

fix: fixes timing issues with debouncer: new debounced functions may start before the previous had finished by @janthurau in https://github.com/ueberdosis/hocuspocus/pull/1014
fix: make beforeSync not async, as this may break message processing … by @janthurau in https://github.com/ueberdosis/hocuspocus/pull/1015
feat: adds lastChangeTime on document which can be used to identify the last time a document has had changes

Note: This changes the behaviour of debounce and beforeSync. Debounce will now make sure that a storeDocumentHook can't run concurrently, and beforeSync is not awaited anymore, as this breaks message order. This will probably be fixed again in the future, once either Yjs has improved observers with missing updates, or once we have implemented messaging ordering.
