feat(server): better support for parent stops

Browse source 
- add datafixer to add parent stops for likely candidates
  - this is mainly for bus hubs, the heuristic is the existence of a
    platform code and missing parent
- use parent stops as default in route_stops
- support parent stops for stoptime querying
