PEtab lint requires indices

[PaulJonasJost]

I noticed that petab_lint requires for some tables specific indices (see e.g. check_observables_df line 301). I was wondering whether there is a specific reason for this or whether one could relax this to the corresponding column (in the example case observableId).

The reason is mostly that it's somewhat annoying to deal with different inputs in every function. If you load a PEtab problem using Problem.from_yaml, the index will be set correctly. If you want to load individual tables, you can use the get_XXX_df() functions, which will do the same. You can pass either a path or an existing DataFrame.
