Feature/fieldcompare

Using fieldcompare will allow some more comparisons than previously possible, e.g. binary VTUs or different mesh formats supported by meshio, e.g. comparing Gmsh msh files, or CSV data with given delimiter.

• Install fieldcompare in CI images
• Fix reference solutions where there is some field name mismatch
• Add and propagate option to ignore fields
• Run pipeline that runs all tests (https://git.iws.uni-stuttgart.de/dumux-repositories/dumux/-/pipelines/25800, DUMUX_SKIP_TEST_SELECTION=yes)
