Feature/json logger

[RuanJohn]

What?

Created a logger that can write data from the evaluator process to a structured json file.

Why?

This will enable for the usage of the EMARL repo tools library for aggregating and plotting Mava experiment data. And for the sharing of raw experiment data which is part of following the suggested evaluation protocol as outlined in the EMARL paper.

How?

Created a JSONLogger class which gets instantiated and added to the evaluator process in the Logger component of a Mava system.

Extra

Added a dictionary called environment_task_name to the make_environment functions for the debugging environments, SMAC, Flaltand, PettingZoo and RoboCup. The PettingZoo MPE examples also seem to have been removed so I re-added them in this PR as well. close #762
