Even though we stored some backbone information for most of our taxa in the previous steps, we want to start from scratch here and retrieve it from GBIF again, as 1) some taxon keys in
verificationKeys will be new and 2) we want to store more attributes per taxon this time.

Preview merged information:
- Number of taxa: 3905
- Some taxa are purposely excluded in a source checklist (e.g. see this issue for Alien birds), but still end up in the unified checklist because they are incorrectly included in another no-longer-updated source checklist (e.g. RINSE pathways). Here we explicitly remove those taxa:
Number of removed taxa: 3
