Merge with react-native-firestack?

I am wondering what you think about merging this library with [**react-native-firestack**](https://github.com/fullstackreact/react-native-firestack)?

Personally, I would enjoy if there would be ONE library for react-native that covers the whole feature set of Firebase. Currently, react-native-firestack seems to be the most mature library with the biggest coverage. Mostly cloud messaging and push notifications are still missing and work on them has been started, but I think in terms of notifications this library (react-native-fcm) seems to be much more mature already and could potentially be merged into firestack.

IMHO, that would combine the efforts of the authors and the community and I think there would be synergies if everybody would work on one project instead of having 3-4 partly implementations.

What do you think?
