Crate global_digital_address 

global_digital_address Square-cell Web Mercator encoder/decoder for globally unique grid codes.

API:

• get_digi_pin(lat, lon, levels) -> String
• get_lat_lng_from_digipin(code) -> Result<LatLng, Error>
• constants: DIGIPIN_GRID, MAX_LAT
• approx_cell_size_meters(levels)

Notes:

• Uses Web Mercator (EPSG:3857) math identical to the JS reference.
• Longitude normalized to (-180, 180]; latitude clamped to ±MAX_LAT.
• Grid subdivision is 6×6 per level.
