Attach route information to schedule data

[kylebarron]

Attach route id, operator id, mode of transit. Maybe share as protobuf? Then when you select the filters in the left, the animation should update. Probably good to have the data filtering in a worker then? Or can you use deck's DataFilterExtension? I'm not sure if it works with strings...

You already load the routes data in ssp_geom.py, so you can just attach the route properties easily.
