Is your feature request related to a problem? Please describe.
No.
Describe the solution you'd like
Firestore integration

Describe alternatives you've considered (optional)
Custom implementation of similar nature.

Additional context (optional)
We required fine-grained authorization system for one of our clients for an application hosted on Firebase, utilizing Firestore as the primary datastore. One of our engineers at FreeTech (@n-hendriks) found this library. After reading through your Mongo integration, I can probably implement something similar with firestore this week. I figured we could write the code to follow your convention, and contribute a firestore integration to the library.

If you all are interested in merging something like this into the master branch, please let me know. I'll send a PR that follow the contributing guidelines.

Hey, sorry for the long delay.

Can you suggest API? Id like to clarify:

1. Regular case when there are matches rules
2. case when there are matching rules. Db query must return empty result set
3. what operators can be supported?

No worries! We ended up going with a custom solution (similar-ish to casl) with Firestore. I am a bit busy ATM but am happy to contribute something similar to the Mongo integration for Firestore when I get a chance, if it's of interest.
