Geohash encode / decode API

Encode a lat/lon to a base32 geohash at a chosen precision, or decode a geohash to its bounding box, center, error margins and the 8 neighbouring cells — the bit-interleaving base32 math LLMs get wrong, computed deterministically. Answers 'what is the geohash for these coordinates', 'decode this geohash to lat/lon', 'what are the neighbouring geohash cells', 'bounding box of geohash u4pruydqqvj'.
