Toll exceptions not taken into account for specific transport types

Hi,

Looking into [OSMTollParser](https://github.com/graphhopper/graphhopper/blob/master/core/src/main/java/com/graphhopper/routing/util/parsers/OSMTollParser.java) it seems GH is not taken into account the toll exceptions like in Itchen Bridge (Southampton):

[OpenStreetMap](https://www.openstreetmap.org/way/9703382)

The idea is to take that exceptions into account and be able to use it on the definitions of custom profiles.

Thanks
