[models] Add a blue "waypoint" 
{launch] Add launch files to launch a single rover and multiple waypoints, and launch parrallel simulations with multiples rovers and multiples waypoints (the cameras fps in parrallel simulations are not keeping up with their 30 fps settings and can go under 1 fps...)

[world] Add the gazebo_ros_state plugin to the isae world to be able to get and set model states.
[script] Add a python script that get and set the position of a list of model names given in parameters
[cmake ] Remove unused dependency to rviz2

TODO: verify and ajust values of simulated depth and rgb with reality.

[worlds,launch] add launch file for launch irobot_01 with telemeter in the autonomous system platform in gazebo.

add Louis support sensors.

[models] create some models like block you can use for add or create a new world...
[launch] modif launch file, now load this defaut world.

Update models and worlds

See merge request !2

Add namespace to ros_planar_move plugin
Fix indentation
Fix rover nosedive by increasing its wheel base
Fix camera position in rover_camera

[world] - correct isae_fisa.world

update light in isae_fisa.world

add terminal markdown.

Environment of room 07-009.
clone this (ros2) package in a colcon workspace, compile, source, and you can launch directly with:
ros2 launch isae_simulations_pkg load_testlabo_world_into_gazebo.launch.py

Once you have launched the simulation, you can retreive models in gazebo insert tab and add into the world.

[models] - Add model of rover and sensors (lidar and camera).

TODO:
add others models in models dir.
add others worlds in worlds dir.
