[BUG] CM11 traffic obj in CM13 will cause co-sim slower than real time

[cjffly]

Describe the bug
We notice CM13 co-sim with SUMO is slower than real time. It happens to be the testrun have 100 traffic obj that is inherit from CM11.

hot fix
I delete all traffic objects in the testrun, and using CM13 GUI to add 30 default traffic objects, set them to free motion and rename them as RS_CXXX.

Initial tests shows with 30 default vehicles, co-sim can run in real time.

Additional context
Comparing with CM11 and CM13 traffic objects in testrun, there are a few lines are differnt. Suggest to re-write the traffic generation python scripts to match CM13 traffic obj definition style.

Here attached CM11 testrun traffic and CM13 testrun traffic:
