/**
 * @name subISOWeekYears
 * @category ISO Week-Numbering Year Helpers
 * @summary Subtract the specified number of ISO week-numbering years from the given date.
 *
 * @description
 * Subtract the specified number of ISO week-numbering years from the given date.
 *
 * ISO week-numbering year: http://en.wikipedia.org/wiki/ISO_week_date
 *
 * ### v2.0.0 breaking changes:
 *
 * - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
 *
 * - The function was renamed from `subISOYears` to `subISOWeekYears`.
 *   "ISO week year" is short for [ISO week-numbering year](https://en.wikipedia.org/wiki/ISO_week_date).
 *   This change makes the name consistent with
 *   locale-dependent week-numbering year helpers, e.g., `setWeekYear`.
 *
 * @param {Date|Number} date - the date to be changed
 * @param {Number} amount - the amount of ISO week-numbering years to be subtracted. Positive decimals will be rounded using `Math.floor`, decimals less than zero will be rounded using `Math.ceil`.
 * @returns {Date} the new date with the ISO week-numbering years subtracted
 * @throws {TypeError} 2 arguments required
 *
 * @example
 * // Subtract 5 ISO week-numbering years from 1 September 2014:
 * const result = subISOWeekYears(new Date(2014, 8, 1), 5)
 * //=> Mon Aug 31 2009 00:00:00
