Outgassing handled by CALLIOPE and other minor additions

[nichollsh]

• Outgassing calculations are now handled by CALLIOPE, a new outgassing module. This means that we no longer need surface_gases.py. Closes Remove surface_gases.py and import CALLIOPE #174
• Added some new configuration files
• Updated examples
• Minor fix to units of R_star when using Baraffe tracks via MORS
• Added a script (tools/PostprocHighres.jl) for post-processing completed simulations with a high resolution spectral file using more complete opacities. Closes Post-process model outputs with high resolution spectral file #175
• Updated docs

Some weird behaviours with the GitHub actions not finding the calliope package. Will investigate, but removed review requests for now

Hi @nichollsh, there is at list one mistake in the pyproject.toml file of Caliope that can explain not finding the paths:
Replacepackage-dir = {"proteus" = "src/calliope" }
By package-dir = {"calliope" = "src/calliope" }

[nichollsh]

Thanks for the suggestion, @lsoucasse. This has worked, and the PR is now ready for review.

All plots in examples/dummy look the same. Could you confirm they are different?
Same comment for examples/earth_demo pdf files.

[nichollsh]

They probably are indeed the same as before, since this PR doesn't change any of the physics involved in running the simulations. The only changes related to that are ensuring that PROTEUS doesn't try to plot the atmosphere fluxes and structure when using the dummy model.

[nichollsh]

I did re-run the examples to make sure that they were generated with a recent version of the code, although this would be better solved by #165

[lsoucasse]

Hum... the csv output displays small differences. So I guess it is fine to upload the new plots.

[nichollsh]

It does - that's interesting. The differences are quite small, but I think this is something we should keep in mind, especially as we get closer to setting up proper tests for PROTEUS.

Thanks!
