Fix up a few warnings, etc. that have accumulated.
We do technically make a breaking API change here: we remove rubbl_casatables::NotScalarColumnError. However, this type has been folded into rubbl_casatables::TableError, and nothing creates it anymore. (It's a holdover from the switch to anyhow.) I don't think anyone should have any code that references this type anymore.
