International street address parser for 220 jurisdictions (US, CA + 218 countries and territories), with SEC EDGAR country-code resolution

/**
 * Greenland (GL) address configuration.
 *
 * Greenland is a Danish autonomous territory and uses the Danish postal system,
 * but its street/building grammar is distinctive:
 *   - Street name FIRST, then the premises identifier AFTER. Greenlandic street
 *     names are long single or multi-word Kalaallisut/Danish words
 *     ("Aqqusinersuaq", "Jens Kreutzmannip Aqqutaa", "Imaneq") and carry no
 *     productive fused generic, so the type is NOT parsed (typePlacement "none").
 *   - Older stock and settlements identify a building by its "B-number"
 *     (bygningsnummer), e.g. "B-1140". When the premises token is a B-number it
 *     is emitted as `building` (via postNormalize) rather than as `number`; a
 *     plain "10" / "10A" stays in `number`/`civic_number_suffix`.
 *   - Postcode is 4 digits, the first two always "39" (3900-3992), written
 *     BEFORE the city ("3900 Nuuk"). No "GL-" prefix is used domestically.
 *   - No state/region.
 *
 * Sources: Wikipedia "Postal codes in Greenland" (GL, 4 digits, "39"..);
 * ResearchGate (house-number + B-number plates on Nuuk buildings); Smarty
 * (https://www.smarty.com/global-address-formatting/greenland-address-format-examples);
