develop method to automatically add a taxonomic checklist (e.g., study, taxonomic authority) to the BTA as an authority

[jhpoelen]

currently, we have some authorities: MSW3, HMW2019, etc.

We'd like to develop a method to (semi-) automatically add other authorities to into the BTA.

For instance, we'd want to add the ITIS taxonomy including all taxonomic notes, references, and add this the to the appropriate treatment/taxonomic concept in the BTA datasets.
