In addition to the current path of:

MyBucket/<project_id>/<ISO-8601_timestamp>/<event_collection>/<project_id>-<event_collection>-<ISO-8601_timestamp>.json.gz

Would also be nice to support the alternate (athena and co friendly) path of of:

MyBucket/<project_id>/<event_collection>/<ISO-8601_timestamp>/<project_id>-<event_collection>-<ISO-8601_timestamp>.json.gz
