I am not quite happy with how this looks right now but at least both
validation examples are for the most part condensed to only differ in
their refinement setup.

Perhaps a SchaeferTurek-specific "Solver" would further improve
reproducibility?

Weirdly it seems easier to get reasonably close values for the unsteady
flow. Results for the steady flow seem to get worse when increasing
grid resolution even in uniform grids.

Cylinder diameter is now actually set to 0.1m as called for by [SchaeferTurek96].

Somewhat fiddled together but works as expected. Refinement areas are
informed by Knudsen metric results. The key is to refine the outflow.
Sadly this requires refinement-overlap-crossing boundary conditions.

Interface for detailed (i.e. cell-relative) grid refinement control
still has room for improvement. Mixing physical indicators and cell
alignment requirements is problematic.
