/**
 * @name eachHourOfInterval
 * @category Interval Helpers
 * @summary Return the array of hours within the specified time interval.
 *
 * @description
 * Return the array of hours within the specified time interval.
 *
 * @param {Interval} interval - the interval. 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
 * // ]
