/**
* @name addISOWeekYears
* @category ISO Week-Numbering Year Helpers
* @summary Add the specified number of ISO week-numbering years to the given date.
*
* @description
* Add the specified number of ISO week-numbering years to 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 `addISOYears` to `addISOWeekYears`.
* "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., `addWeekYears`.
*
* @param {Date|Number} date - the date to be changed
* @param {Number} amount - the amount of ISO week-numbering years to be added. 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 added
* @throws {TypeError} 2 arguments required
*
* @example
* // Add 5 ISO week-numbering years to 2 July 2010:
* const result = addISOWeekYears(new Date(2010, 6, 2), 5)
* //=> Fri Jun 26 2015 00:00:00
