parse fns: individual params -> data object 💥

From now on, all higher-level parse fns will be able to access more
of the response data while keeping their signature.

- parseLine
- parseDeparture
- parseJourney
- parseJourneyLeg
- parseLocation
- parseMovement
- parsePolyline
- parseNearby
- parseStopover
