Usage with a secondary firebase app

[dereklance]

Is it possible to use this library with a secondary firebase app for auth? My primary firebase app is only used for analytics, and to do so I need to provide the path to my GoogleService-Info.plist and google-services.json files in my app.json. However, this library expects those files to be used for auth which I don't want. Basically I need a way to configure the GoogleSignIn instance at runtime with a different GoogleService-Info.plist and google-services.json somehow
