Stats

Add scripts for computing and viewing some statistics

LGTM, at least I can't think of anything important that we would be absolutely missing.
For reference, this was the script we once used to obtain some statistics:

SELECT l.distance as besetztkm, l.distance*request.passengers as personenkm, l.duration as besetztzeit, (tour.arrival-tour.departure)/1000 tourzeit, tour.departure as tour_start_ts, tour.arrival as tour_end_ts
FROM journey
JOIN request ON request.id = journey.request1
JOIN tour ON request.tour = tour.id
JOIN LATERAL jsonb_to_recordset(journey.json -> 'legs') AS l(distance numeric, duration numeric, mode text) ON true
WHERE NOT tour.cancelled
  AND NOT request.cancelled and request.ticket_checked  and l.mode = 'ODM';

I think this could also be interesting for cancelled tours?

I agree. So far I avoided touching this since, #582 means there might be tours for which it is not trivial to tell which requests belonged to it before it was cancelled. So I will probably look at this issue before merging this.
