Support for new Firestore "collection group" query

[sampl]

👋

Would love to use the new Firestore collection group feature in react-firestore

https://firebase.google.com/docs/firestore/query-data/queries#collection-group-query

something like

import Firebase from 'firebase/app'	
import React from 'react'	

 class FirestoreCollectionGroup extends React.Component {	

   state = {	
    isLoading: true,	
    error: null,	
    data: null,
    snapshot: null,
  }	

  componentDidMount() {	
    this.unsubscribe = Firebase.firestore()	
      .collectionGroup(this.props.path)	
      .where(this.props.filter[0], this.props.filter[1], this.props.filter[2])	
      .onSnapshot(this.handleBoard, this.handleError)	
  }	

   componentWillUnmount() {	
    if (this.unsubscribe) {	
      this.unsubscribe()	
    }	
  }	

   handleBoard = snapshot => {	
    this.setState({	
      isLoading: false,
      data: snapshot.docs.map(docSnap => docSnap.data()),
      snapshot,
      error: null,	
    })	
  }	

   handleError = error => {	
    this.setState({	
      isLoading: false,	
      data: null,
      snapshot: null,
      error,	
    })	
  }	

   render() {	
    return this.props.children(this.state)	
  }	
}	

export default FirestoreCollectionGroup

Actually just ran into a problem with collectionGroups and may not use them after all, but leaving open in case others have a need
