Cratea a data quality issue reporting form

[jbruechert]

We depend on external parties to get accurate timetable data.
Data quality issues (like wrong times, inaccurate stop positions etc.) should be reported to whoever creates the GTFS-feed.

It would be nice to have a service to which apps could pass a MOTIS trip id, that automatically fetches the trip from MOTIS and figures our the correct issue report address. Contact addresses can be found in https://routing.spline.de/gtfs/license.json.

The MOTIS "source" json attribute can be matched against the filenames in license.json to pick the right list of contact addresses.

The extracted list of contact addresses should then be consumed as follows:

1. Use publisher address if it exists. The agency might be unaware of
   the feeds existence, and writing to them will not help.
2. Pick the agency with the matching agency_id if it exists.
3. Use a contact address with type "attribution". It should be manually
   checked whether this is applicable.

The app can then ask the user to send an e-mail to the correct address, possible with an autogenerated template message.

Contact addresses can be found in https://routing.spline.de/gtfs/license.json.

For now a lot of email addresses seem to be missing, so a first step would be to add them.

They are taken from the GTFS files, so either we add them ourselves using our metadata or ignore these operators in the reporting tool

As a fallback to an official feedback channel (or if we know the respective data provider is known to be responsive in public issue trackers), we could refer to the GTFS-Issues repo, in order not to create yet another place for feedback to end up.

It has long been Germany-specific, but @hbruch and I intend to widen its scope anyways. We could add some transitous-specific questions to the Issue templates or add a new separate Issue template.
