need to account for splits and merges in BTA

For instance Pteronotus parnellii currently has an agreement index of 1.0, which does not account the splits.

Pteronotus parnellii was split into 8 species (e.g., mesoamericanus . . . )

Solution is to put the name Pteronotus parnellii in MSW3 column of the Pteronotus mesoamericanus row.

See attached screenshot.

Then we should be albe to update the agreement index to reflect what we know about this Pteronotus parnellii name in that was split and is therefore problematic when encourered in old literature / observations.
