Try installation on Linux

Hello there,

fyi I can confirm that the tutorial scripts for Didymos and Moon work as expected in Linux, specifically in Ubuntu 24.04 with python 3.11.10 and all module requirements pip automatically installs. I tried both following the installation instructions as you wrote in the README and installing the module manually (both cases in a virtual-env).

Just a couple of very minor things you may want to change:

1. The OBJ files for S05_Didymos downloaded from Drive have the extension in capital letters (.OBJ) which must be manually modified for the tutorial script to run.
   

2. The tutorial script S05_Didymos expects a material filename that does not match with the file in the scenario folder and must be manually changed.
   
   

3. An error is thrown by bpy at import time, possibly related to my case only. Anyhow it appears to be handled and not to cause troubles in using cortopy. Error message here:

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.1.3 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

4. In general, I modify the entry in .gitignore: .venv/ to a more convenient (for me) .venv*/
