This refactor should better handle multi-coordinate indexes when updating (or assigning) new coordinates.

It also fixes, better isolates and better warns a bunch of deprecated pandas multi-index special cases (i.e., directly passing pd.MultiIndex objects or updating a multi-index dimension coordinate). I very much look forward to seeing support for those cases dropped :).
