Enable a dynamic range search for matched way points

[afischerdev]

This should enable the #387 issue.

It could be tested on the BRouter test server together with the #728 and #726 Sample

The logic is only valid for the first and the last point. So please test 2 points routes only at the moment.

For a dynamic range test you will need a new profile constant

assign use_dynamic_range   = true  # %use_dynamic_range% | Enable distant start/end points | boolean

Please remember to test #728 with this entry

assign check_start_way      = true   # %check_start_way% | Activate a test for the starting way | boolean | noStartWay=route,ferry;highway,motorway;highway,motorway_link
