Support snapping to multiple ways at an input location

Browse Source 
This PR improves routing results by adding support for snapping to
multiple ways at input locations.

This means all edges at the snapped location can act as source/target
candidates for routing search, ensuring we always find the best route,
and not the one dependent on the edge selected.
