See [Interval]{@link https://date-fns.org/docs/Interval} * @param {Object} [options] - an object with options. * @param {Number} [options.step=1] - the step to increment by. The value should be more than 1. * @returns {Date[]} the array with starts of hours from the hour of the interval start to the hour of the interval end * @throws {TypeError} 1 argument required * @throws {RangeError} `options.step` must be a number greater than 1 * @throws {RangeError} The start of an interval cannot be after its end * @throws {RangeError} Date in interval cannot be `Invalid Date` * * @example * // Each hour between 6 October 2014, 12:00 and 6 October 2014, 15:00 * var result = eachHourOfInterval({ *   start: new Date(2014, 9, 6, 12), *   end: new Date(2014, 9, 6, 15) * }) * //=> [ * //   Mon Oct 06 2014 12:00:00, * //   Mon Oct 06 2014 13:00:00, * //   Mon Oct 06 2014 14:00:00, * //   Mon Oct 06 2014 15:00:00 * // ] */export default function eachHourOfInterval(  dirtyInterval: Interval,  options?: StepOptions): Date[] {  requiredArgs(1, arguments)
