Comm msg

[JaehyunShim]

1. Duplicated the same type of data. Recommend removing the one in ContactPhaseData
   https://github.com/thomascbrs/memmo_anymal/blob/main/walkgen/GaitManager.py#L50
   https://github.com/thomascbrs/memmo_anymal/blob/main/walkgen/GaitManager.py#L69

2. We need to consider applying naming conventions to these communication messages as well as all the code in the pipeline.

3. Created ROS comm msgs for it (https://github.com/JaehyunShim/memmo_planner_ros/tree/main/footstep_msgs)

@JaehyunShim could you give me access to the repo reported in point 3?

I would like to quickly review the code.
