MOTIS: Implement support for mode filtering

[jbruechert]

The Norway dataset contains flights, which make it impossible to find train connections there because they are always faster.

We need to be able to filter those out.

Personally, I wouldn't necessarily want to filter those out, but rather expand the set of Pareto criteria so that they appear alongside train/bus connections, with all their trade-offs.

[jbruechert]

Depending on what is more realistic, that is of course fine as well.
But I think having filtering is good nevertheless, for use cases like local tickets, interrail etc.

My guess: performance is better if you just start two separate searches, one with flights allowed, one with flights not allowed and then merge them to become one Pareto-set. Different approach, same results, better performance for the user (and no significant changes to the actual routing algorithm).

Implemented here:

motis-project/motis#453
https://github.com/motis-project/motis/releases/tag/v0.11.21

My guess is that you can produce long running queries by enabling only local bus usage and routing through Europe.

Thank you, that was really fast!

I guess this can be closed.
