Now I understand this PR's change keeps (tmat, origin_shift) in the normalizer of the MSG because ref_find_similar_bravais_lattice only tries operations in XSG or FSG or the MSG.

The Bravais lattice for a magnetic space group is chosen approximately randomly when symmetrically equivalent options exist. This can change the orientation of the input cell even if it is already standardized, which is non-intuitive. This PR addresses this issue by preserving the cell orientation when possible.
