feat(android): firestore database

[m1ga]

Following up the Firestore Database query method I'm adding more methods

updateFirestore to add or update documents:

FirebaseDatabase.updateFirestore({
        collection: "",
        document: "",
        data: {}
});

deleteFirestore to delete documents:

FirebaseDatabase.deleteFirestore({
        collection: "",
        document: ""
});

Everything still WIP but I need it for a current project :smile: At the moment only the query part (which works fine) but I think we can add some more features too
