Insert Real-world Maps

[amock]

This is a TODO-issue for someone integrating real-world maps into this repository. We should at least add the pluto maps to make the ROS 2 version of mesh navigation backwards compatible with all the experiments done in the old mesh nav papers and Sebastian's dissertation. We could also collect here some instructions on how to use mesh navigation with worlds from other SOTA 2.5D navigation approaches.

Further thoughts:

• Since the pluto real-world maps are large in file size we might start using git-lfs for them (?)

git lfs sounds like a good idea for these large maps

Also, I'm not 100% sure where to put the maps. For now, I would prefer to create a new package so as not to clutter the existing two simple packages. For the Pluto maps, that would be something like “mesh_navigation_tutorials_pluto_sim” and “mesh_navigation_tutorials_pluto”. I would do it this way because I think the existing two packages encapsulate all the scenarios that run very smoothly on low-end computers. Adding the real maps to the existing packages would violate this.
