Lane Handling for multiple indications per lane as in left;left|, fixes #2694

Browse Source 
Before we asserted on unique lane indications per lane. Turns out the
OSM data contains lane strings such as:

    left;left|right

Which represents two lanes as in:

    <<     >
     ||    |

The two left indications _on a single lane_ look like data issue.
And we can't represent this with our enum-approach at the moment.

We don't want to crash there, so silently swallow this and
generate a single left|right for it.
