This PR adds support for Trixi simulations on spherical shells. See trixi-framework/TrixiAtmo.jl#25.

@amrueda is this ready to merge? It would be nice to have this so we can use it with TrixiAtmo.jl.

Since Trixi2Vtk.jl calls Trixi.calc_node_coordinates!, plotting 2D surfaces in 3D will not work until Trixi.calc_node_coordinates! can handle this case. I currently have a PR for Trixi.jl at trixi-framework/Trixi.jl#2068 which addresses this for P4estMesh. No changes would need to be made to this PR for Trixi2Vtk.jl if that is merged.

Since trixi-framework/Trixi.jl#2068 was merged, I guess that we are ready to merge this PR?

Please add a comment explaining why we need this convoluted way and cannot just use ndims_.

Also, please be consistent with our formatting conventions (space after comma).

Finally, please do not use abbreviations in variable/type/function names that are not absolutely clear to everyone in the community (unless you are really referring to the town in Belgium).

As before, please leave a short comment explaining this seemingly overcomplex way of setting the number of dimensions.
