gtfstools v1.2.0

New features

• New validate_gtfs() behavior. Now used to run MobilityData Canonical GTFS
  validator with a feed. The old behavior was marked as deprecated since
  v1.0.0.
• New function download_validator().
• New vignette demonstrating how to validate feeds.

Bug fixes

• Fixed a bug in write_gtfs() that prevented as_dir = TRUE to be used.
• Fixed a bug in set_trip_speed() that resulted in invalid stop_times tables
  when max(stop_sequence) was higher than the number of stops of a given
  trip. Thanks Alena Stern (@alenastern).
• Fixed a bug in set_trip_speed() that resulted in the speed of wrong
  trip_ids being updated because of the order that these ids would appear in
  the trips and stop_times tables. Thanks Alena Stern (@alenastern).
