journeys(): support multiple via points

[yu-re-ka]

I don't know the api format needed for this, but it should be possible to enter multiple via points

We could change the code to handle opt.via being an array. This is the current implementation:

hafas-client/index.js

Line 144 in 9c10a17

if (opt.via) opt.via = profile.formatLocation(profile, opt.via, 'opt.via')

[fightforlife]

should multiple via points in an array handled as AND (the journey has to go through all via points) or OR (Journeys can go through either point)

[derhuerst]

Note sure! Do we know if HAFAS supports both? Would be great if someone could investigate this!
