@nbillietPM discovered that some OTT IDs in the OTL database map to multiple GBIF IDs, indicating a one-to-many relationship. It is therefore not advisable to rely on the relationship in OTL and instead match the tip labels to GBIF species directly using rgbif. The taxonmatch() function needs to be rewritten and the use of OTT_id's in the subsequent functions of the workflow need to be replaced with GBIF usageKeys.
