Add object LaneletNetwork to Scenario is broken
The function to add an object type LaneletNetwork to a Scenario does not correctly update the id set of the scenario. Only lanelets are marked while since 2020.1 also traffic signs and traffic lights and intersections are part of a LaneletNetwork and do have ids.
- Iterate through all four member sets
- introduce a set_id object for lanelet networks and copy its ids over
