/**
 * Formats a Brazilian license plate (placa de carro ou moto).
 *
 * Old format plates ("LLLNNNN") are hyphenated, while Mercosul plates ("LLLNLNN") are
 * returned without any separator. Partial values are formatted as far as they go, so the
 * function can be used as an input mask.
 *
 * @param {string} value - The license plate to be formatted.
 * @returns {string} The formatted license plate, or an empty string when the value cannot
 * start a valid license plate.
 *
 * @example
 * ```typescript
 * formatLicensePlate("abc1234"); // "ABC-1234"
 * formatLicensePlate("abc1d23"); // "ABC1D23"
 * formatLicensePlate("1234567"); // ""
 * ```
 *
 * The `AAA-1111` shape of the old PNU is art. 2º § 3º of Resolução CONTRAN nº 969/2022; the
 * separatorless `LLLNLNN` shape of the Mercosul plate is item 1.2 of its Anexo I, published in a
 * PDF of its own. Both are cited below.
