Update data-types.md

MDS Events
- removed gtfs_route_id, gtfs_trip_id, gtfs_service_id, gtfs_api_url; These can all be found by linking to MDS trips with MDS trip_id.
- removed stop_sequence; We can get this information ourselves using the stop_id and timestamp fields for each MDS trip_id so this field doesn't need to be part of the spec

MDS Telemetry
- removed gtfs_route_id, gtfs_trip_id, gtfs_service_id; These can all be found by linking to MDS trips with MDS trip_id.

MDS Trips
- remove gtfs_route_id, gtfs_service_id, gtfs_shape_id; These can all be found by linking to GTFS trips with GTFS trip_id and the GTFS API URL.
