redlist: Interface to the IUCN Red List Data with Risk Metrics

Access species conservation data from the International Union for Conservation of Nature (IUCN) Red List API <https://api.iucnredlist.org/api-docs/index.html>, including assessments, taxonomy, threats, habitats and historical status. The package also reconciles taxonomic names between the IUCN Red List and the Global Biodiversity Information Facility (GBIF), retrieves and checks GBIF occurrence records, and computes the range and population metrics of the IUCN Red List Categories and Criteria (IUCN Standards and Petitions Committee, 2024, <https://cmsdocs.s3.amazonaws.com/RedListGuidelines.pdf>): extent of occurrence and area of occupancy for criterion B, and population reduction for criterion A.
