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

/**
 * Cameroon (CM) address configuration.
 *
 * Language: French (official administrative language for addressing, alongside
 *   English in the anglophone NW/SW regions).
 * Order: house number FIRST, then the voie type + name ("10 Rue Joffre").
 *   Numbers are frequently ABSENT -- many Cameroonian streets are unnumbered, so
 *   a bare "Boulevard du 20 Mai" is the norm.
 * Type: leads the street name (prefix), French vocabulary (Rue, Avenue, Bd, ...).
 * Postcode: NONE. Cameroon has no operational postal-code system (CAMPOST does
 *   not route on postcodes), so the postal slot never matches.
 * Region: optional -> state. The 10 regions (Centre, Littoral, Ouest, ...) are
 *   rarely written but supported after the city.
 * PO box: "B.P." / "BP" (Boîte Postale) is the DOMINANT delivery form
 *   ("B.P. 1234, Douala"); the box number is not a house number.
 *
 * Sources: CAMPOST; UPU S42 addressing notes; Smarty / PostGrid Cameroon guides;
 *   exampleaddress.com Cameroon corpus. See research-cm.md.
