Fix CMC consensus pose estimation and refinement

[cfs-data]

Consensus algorithm fixes

• Apply the correlation threshold as a post-filter, like the median classifier does.

• Fixed _refine to return the updated inlier set and criterion instead of None.

• Fixed the consensus rotation sign, which was negated relative to the median classifier.

• Fixed the consensus translation, which was only valid at the fit centroid. Added get_translation_about to express it around the reference center, and dropped ConsensusParameters.translation.

• Fixed the single-CMC pose, which took cells[0] instead of the congruent cell.

• Fill cell.meta_data, which was left at its defaults. Moved wrap_angles to utils.py and wrapped the consensus angle residual too.

• Report NaN for the pose if no consensus geometry
