Add option to (top-level) filter `meta` by model and scenario #71

Closed danielhuppmann closed 7 months ago

As I wrote in #66, I believe that it is more intuitive to filter like

platform.meta.tabulate(run={default_only=True}, model={"name": "Model 1"})

instead of (the multi-nested)

platform.meta.tabulate(run={default_only=True, model={"name": "Model 1"}))

because 1. model and scenario names are part of the Model and Scenario tables (not Run) and 2. because it's less complex.

This PR adds the ModelFiler and ScenarioFilter to the RunMetaEntryFilter. The warning about cartesian products was solved by #69 (it seems).

Note that this PR is directed into #69.
