This will need to be rebased with conflicts resolved. Schema files were moved into the python/lsst/sdm/tools directory.

I'm assuming this was originally intended for inclusion in DP1?

From what I understand, it's now too late for that. What are the prospects for this PR now? The change requested above was just for a typo in the description.

@gpdf this will go in with the full DM-47738 PR. Hierarchical deblending is introduced in scarlet lite in this ticket, so it is an irrelevant field for DP1. But this should be ready for merge soon, dependent mostly on how many emergent issues I work on over the next week or two.
