/**
 * Take `String` and parse it as CSV to generate arrays.
 *
 * See:
 *
 * - {@link CSVObject}
 * - {@link https://github.com/Inist-CNRS/node-csv-string}
 *
 * Input:
 *
 * ```json
 * "a,b,c\nd,e,d\n"
 * ```
 *
 * Output:
 *
 * ```json
 * [
 *   ["a", "b", "c"],
 *   ["d", "e", "d"]
 * ]
 * ```
 *
 * > **Tip**: see CSVObject, to convert arrays of values to array of objects.
 *
 * @name CSVParse
 * @param {String} [separator=auto] to indicate the CSV separator
 * @param {String} [quote=auto] to indicate the CSV quote.
 * @returns {Array<String[]>}
