GTFS importer : waiting for calendar.txt which is not mandatory (calendar_dates.txt)

[Art-Ev]

Was using qaequilibrae but I think it's a library problem :

Trying to import a GTFS : https://data.toulouse-metropole.fr/explore/dataset/tisseo-gtfs/table/

Cannot be processed :

TypeError: 'empty' object is not subscriptable

GTFS importer is working only with calendar.txt but GTFS allow usage of calendar.txt with optionnal calendar_dates.txt OR only calendar_dates.txt

There was a calendat.txt file but empty, if I delete it aequilibrae is still looking for it :

KeyError: "There is no item named 'calendar.txt' in the archive"

Hey @Art-Ev, when AequilibraE's GTFS module was added, the calendar.txt file was a mandatory requirement. It has to be updated to include either calendar.txt or calendar_dates.txt as in Toulouse GTFS. I'll add a bug tag to the issue to update GTFS-required files in the importer.
