✨ Improved
This version makes several improvements to `XMatch`:
* Removes some hard-coded use of SQL files. These should not be necessary and if they were, we should get to the bottom of why they are ...
* Store intermediate results in a sandboxed `catalog_to_XXX` table. This allows to run a full dry-run cross-match for a single catalogue.
* Phase 1: distinct only on `model_pk`.
* Phase 3: Require using only best matches.
Additionally, this version adds the `too` carton.
