This PR slightly changes the merging logic. It checks to see which units are mergeable (wrt to the sparsity threshold) before trying to merge.
Now we warn and don't merge the units, rather than error the entire process, if individual units cannot be merged.
I tried implementing this inside of
_save_or_select_or_merge_or_splitbut it was a mess. I think it's best to know your new unit ids and final merge groups before this function is called.@samuelgarcia @yger feedback welcome! I need to add some tests...
