Fix invalid gtfs file caused by agencies not in hardcoded list (#95)

The timetable can contain routes not in the hardcoded list in
agencies.ts. In particular I've seen QH, QR, QU, and QV in the national
rail data portal timetable.

This commit exports such routes using the existing 'ZZ' - Other operator
agency.
