Spawning multiple robots in the same aquatic environment

[ruipaulorocha]

Dear VRX developers and maintainers,

As far as I understood, current set of available launch files in the VRX GitHub repository do not support spawning multiple WAM-V robots in Gazebo Garden simulator and pushing the ROS topics and TF tree of each robot to its separate namespace (e.g. robot_0/, robot_1/, etc.). Do you confirm?
Are there any plans to support this in the near future?
Do you have such a multi-robot system example that can be shared in the repository?
