TODS-I501

GTFS trips have no run event

INFO

Needs a companion GTFS feed. Opt-in: off by default, enable with --enable coverage or --enable TODS-I501.

Some trips in the companion GTFS feed are never referenced by a run event, so no crew work is described for them. This is informational: not every trip must appear in run_events.txt, but wide gaps can mean an incomplete export.
