Script to load existing data from firestore to bigquery. It works for collections and subcollections.

This script is modified from https://github.com/firebase/extensions/blob/next/firestore-bigquery-export/scripts/import/src/index.ts#L188 . The script is modified by https://github.com/MattReidArnold .

The official script is not yet modified and PR is still not merged. So, i created this repo.
