Firebase recently added opportunity to use iOS Game Center for authentication

https://firebase.google.com/docs/auth/ios/game-center

Alongside already existing Android Play Games authentication method https://firebase.google.com/docs/auth/android/play-games, two of these make perfect sense to be used in game projects.

After looking at RNFirebase source I don't believe these methods are implemented?

What would be a strategy to add them in? I could look into Game Center support.
