CDASim real-time time sync script also needs to allow post-processing

[MishkaMN]

Summary

We needed data driven method to check whether if all the tools being orchestrated by the MOSAIC is being time synced appropriately. Under VRU use case, we developed a real-time monitor for this. However, the script also needs to work on post-processing mode to allow recreating the images from the logs. This also has benefit of the real-time script not adding extra load on the system while the simulation is running.

Reasoning for new functionality
