Local biodiversity hotspot: top species by observation count API

Ranks the most-observed species within a radius of a lat/lon using iNaturalist's species_counts, returning each species' observation tally plus the total distinct-species count and an iconic-taxon mix. Answers 'what are the most common species here', 'the biodiversity of this area ranked by how often things are seen'.
