Support more top-level messages

[ClemensLinnhoff]

Describe the feature

Currently only SensorData, SensorView and GroundTruth are supported as top-level messages. We should implement also the other top-level messages, e.g. TrafficUpdate, TrafficCommand and TrafficCommandUpdate.

[ClemensLinnhoff]

This needs to be supported in OSITrace, before it can be used here.

Wairing for OpenSimulationInterface/open-simulation-interface#818 to be merged in OSI.
