Check that start_date is consistent with GTFS #42

Summary:

For normal scheduled trips (i.e., not defined in frequencies.txt), make sure that the TripDescriptor start_date matches the GTFS trip start_date - in other words, it must be a valid start date given calendar.txt and calendar_dates.txt. If not, it's an error.

Moved here from #37 (comment).

Note that start_date is actually a little tricky to calculate, because it requires loading/extrapolating calendar.txt as well as calendar_dates (including agencies that just add all service to calendar_dates).

Similar issue exists for frequency-based exact_times=1 trips, ticketed at #41.
