/**
 * Retrieves the region of a PlayStation Network user based on their username.

 * This function uses the npId from the user's profile to determine their region.
 * The region is extracted from the base64-encoded npId and returned as an object
 * containing both the two-letter country code (ISO 3166-1 alpha-2) and the full
 * country name.
 *
 * @param authorization An object containing your access token, typically retrieved with `exchangeAccessCodeForAuthTokens()`.
 * @param userName The username for the user whose region you want to determine.
 * @param locales Optional. A string with a BCP 47 language tag, or an array of such strings.
 *                Defaults to ['en'] (English) if not specified.
 * @returns A promise that resolves to a RegionInfo object with the country code and name, or null if the region cannot be determined.
 *
 * @throws Will throw an error if the user cannot be found or if there are any issues accessing the profile.
