Add lunar pole exploration simulation with realistic solar power

[RBinsonB]

This issue references space-ros/simulation#22 opened in the simulation repo.

There is no moon simulation in Space-ROS yet. A moon simulation could be added.

One subject of interest in particular is the exploration of the moon south pole region. Due to the presence of permanently shaded craters, there is a high chance of water ice being present and that could be used to establish a long lasting human presence on the moon (https://www.weforum.org/agenda/2023/08/space-water-ice-moon-south-pole/).

The NASA VIPER rover mission aimed to explore this area. Unique challenges have to be addressed in this environment and would be interesting to simulate in Space-ROS. In particular the power generation and management:

• Solar power being constantly available outside of shaded area
• Solar power being unavailable while testing the presence of water ice in a shaded area
• Solar panel placement to adapt to the sun low position on the horizon

The issue space-ros/simulation#22 focuses on the different assets to be added for the demo.
In the demos repo, the following element would be necessary for the demo:

• A controller node to fit the unique kinematic and range of motion of the rover with four fully steerable wheels (sideway motion, etc)
• A Gazebo world of the moon (gravity, atmosphere, etc) that would include the rover and a realistic ground from the Mons Mouton (planned sites of the VIPER mission).
• A set of demo services (similar to the ones of the curiosity demo) to demonstrate the different motions and control of the rover.

@RBinsonB I have been participating in the Gazebo Ionic Test party that launched a few days back. I did see a moon's world already prebuilt and if memory serves, the object interacting in it appeared to show signs of object falling on moon. I will be very interested to help you setting up this demo. I have been working with the mars rover demo for sometime now and have become familiar with the drive and steering control architecture used in that demo.
