Add high fidelity Mars & Moon demos

[martincerven]

Use data from MRO or LRO to create new high fidelity simulation environments for Gazebo.

Since highest resolutions for LRO is 50cm/px, investigate if the visual fidelity is sufficient for simulation with robotic rovers.
It can possibly be augmented with Generative AI.

Other possible improvements could be:

• add another space vehicles to simulation
• add better textures for heightmaps
• add models of space station or rocks
• add animated models of astronauts or other vehicles, since spawning many ROS enabled models could be computationally expensive

Additional improvements if there will be enough time:

• add Gazebo plugins to make simulation interactive ( door opening, picking up rocks )
• investigate autonomous movement of rover with nav2 & object recognition

Lastly, it would be very beneficial to create tutorial for people to import existing and any future data from such missions as LRO to Gazebo sim, that would entail:

• describe data preparation
• creating formats suitable for Gazebo
• creating SDF worlds with it
