UTM & MGRS grid reference converter API

Convert a geographic lat/lon to Universal Transverse Mercator (zone, latitude band, hemisphere, easting, northing) and to an MGRS grid reference, computing the WGS-84 transverse-Mercator projection series an LLM cannot evaluate. Answers 'what is the UTM coordinate for this lat/lon', 'convert these coordinates to MGRS', 'which UTM zone is Paris in', 'easting and northing for 48.8584, 2.2945'.
