periodically pull new GTFS data to refresh route shapes and route list

[sidetrackedmind]

The route list and route shapes are static files. It's possible TriMet could add and/or modify a route shape and the data in S3 and/or the route list will be outdated.

Actions:

• Low priority - Periodically grab GTFS shapes and push them to S3. Luckily, the "winning" itinerary shapes are shown so this will only negatively impact bad guess routes
• Grab routes.txt GTFS and re-fill the html dropdown list. TriMet may add shuttle or other service.

Just need to run this notebook periodically.
