5efadb09cc feat(library/tactic/inversion_tactic): improve 'cases' tactic for HoTT library 
This commit adds support for hypotheses (h : C As idxs) where the indices idxs
are just local constants. Before this commit the indices idxs had to be hsets.
Now, they can be hsets or local constants.

The new tests demonstrate new examples that can be handled by the
improved tactic in the HoTT library
