Merged PR 295: Agent action logging

## Summary
Added a new optional capability to create a JSON log each episode with a list of action each agent took each step (including scripted, RL, and red agents).

Also I had to slightly refactor the IO system to not rely on PrimaiteSession, as it's gonna be deprecated soon. Therefore the IO module is now linked to the gym environment. Each time you init a gym environment, it creates a session directory.

## Test process
Tried the SB3, Ray SARL and Ray MARL notebooks to see that the outputs get generated.
