v4.0.0

Release Notes

A big thank you to @andipaetzold who made the underlying changes for this release.

Breaking Changes

• This release updates react-firebase-hooks to support Firebase v9, the new modular SDK from Firebase. Whilst there should be no changes required to the way that you interact with react-firebase-hooks, a number of changes will need to be made to how you interact with the underlying Firebase SDKs.
