Fix stop id for 803N

Stop ID for Republic Square stop for 803N is stale.
For now, we just swap it out with the new stop ID in
`load_gtfs_data.py`.
keep stop data nice and ugly
Unfuck stops, route

Get GTFS file from `https://data.texas.gov/Transportation/Capital-Metro-Google-Transit/8s4f-jd2a`, not `https://www.capmetro.org/gisdata/google_transit.zip`. Train routes aren't right.
