Describe the problem

The GTFS Best Practices include the following best practice:

Remove old services (expired calendars) from the feed.

We don't have a check that looks for expired calendars

Describe the new validation rule

If there exists a row in calendar.txt with end_date < TODAY_DATE, or a row in calendar_dates.txt with date < TODAY_DATE, trigger an "expired_calendar" notice
