RECCES TODO + single-nt-bulge updates
Some integration tests change due to an update in how fold_tree is setup inside fixed domains. connections between end of one chain & beginning of next chain are preferred (this matches the behavior of figure_out_reasonable_rna_fold_tree).
In some swm protein/rna tests, this produces very very tiny floating point errors (1e-7) that accumulate.
