For the MacProjector, allow specifying Robin BCs (since mixed BCs can be viewed as a special case of this).
For (EB)Godunov, this has been implemented by allowing the option to pass a position dependent BC MF/Array4. The BC MF is cell-centered and carries the amrex::BCType type in the first ghost cell (precedent set by MLMG's treatment of Robin BCs) and must fully specify the BC on all faces. If a position dependent BCs are passed in, they take precedent and single bc per face BCRecs are ignored.
