Transit : what's next

After the #953 update, now online, we've listed lots of features to add.

Bonus for a second PR

• [ ] give some human sens to the results of this query : train names, train brands, train numbers
• implement the cycle suggestions as a distance in the UI : instead of talking about bike or car, just show the distance to the station in the results list to open the possibilities to e.g. a friend dropping you or taxi or transport unknown to Motis
• add accessibility pedestrian option & let the user come back to the "auto" mode
• add the "arriveBy" feature
• add the stops in the itinerary mode on the map. Not hard, but share code with the transit plans if possible
• The itineraries attribute is always there with potentially length === 0 It doesn't tell us if there's an agency here. But we could use our agency plans to check that, quite easily
