Traffic Light Sync Problems in WOMD and Waymax Simulation #60

There appears to be a synchronization issue with the traffic lights in WOMD and the simulation in Waymax.

Specifically, the traffic lights' states do not always match the agents' states, causing logged agents to cross red lights. Additionally, agents seem to decelerate at green lights, possibly due to a misinterpreted orange light in the real data.

I have written a script to detect these issues, and while it does produce some false positives, the problem occurs in approximately 10% of scenarios in WOMD v1.1 and v1.2.
