Name duplicates in the 2024-12-19 release

[Mesibov]

Taxon.tsv in the 2024-12-19 release in CLB has a very large number of duplicate names, i.e. records which differ only in taxonID. These are listed in the attached strict-duplicates.txt.

Most of these arise in the source, for example the pair

10 | accepted | subgenus
14 | ambiguous synonym | form
2 | ambiguous synonym | infraspecific name
504 | ambiguous synonym | species

ambiguous synonym is exactly for those cases when the same name is a synonym for different accepted names, i.e. a pro parte synonym. So these are very much expected to be "duplicates".
