Don't highlight all routes

[pyrog]

I use PT assistant to check hiking routes (also MTB, horse, foot… routes).

The pt_assistant layer highlight hiking routes (part of node networks) 😄
… but also bus routes (and probably all routes like MTB, cycling…).

Ot will be useful to have a option to select which type of routes that should be highlighted and/or checked.
