Title: Add support for the HGV route_types extensions.

This pull request ensures backwards compatibility for GTFS feeds that contain HGV route codes in the route_type field and adds a feature to the API representing this value.
Berlin OpenVBB feed is using these codes to distinguish between the types of rails such as S-Bahn, Regionalbahn and Intercity Trains, etc.
