 * @param angle - When a number, the number is assumed to be radians and is returned as is.
 *                When a string, the number is parsed as degrees and converted to radians
 *                as long as the string ends in a lower-case 'd'.
 * @throws - When the string `angle` is malformed.
 * @returns - The provided angle as radians.
