Update how to use ROS

[dehann]

From Slack General, Simen:

Do you have a script of getting the rospy <--> RobotOS.jl to work? The RosbagSubscriber() method doesn't seem to be defined (but I guess this is a method that is defined when the setup is correct?), can't find the method definition of RosbagSubscriber() in either Caesar.jl, RobosOS.jl or RoME.jl, which is used in all the examples (like in the docs here https://juliarobotics.org/Caesar.jl/stable/examples/using_ros/) I'm able to get Caesar.jl and RobotOS.jl to precompile without complaining about not having run the ROS setup.bash, but the RosbagSubscriber still doesn't seem to exist anywhere
