Right now the bag player is basic and all topic share the same thread. This I already know is a problem but I wanted to have something running end-to-end
Add test that: create an mcap bag -> play the bag -> record the bag -> check that the two bags are the same
To do this I create test protofile in the bag test folder. These are very similar to the one that already exists in the serdes module. I will unify them later as I need to find a satisfying way of doing it.
Extendend signal handler utilis to support the case of bag playback where we want to terminate either because the app complete or via signal, please provide better naming!
Description
