* @name formatISO
* @category Common Helpers
* @summary Format the date according to the ISO 8601 standard (https://support.sas.com/documentation/cdl/en/lrdict/64316/HTML/default/viewer.htm#a003169814.htm).
*
* @description
* Return the formatted date string in ISO 8601 format. Options may be passed to control the parts and notations of the date.
*
* @param {Date|Number} date - the original date
* @param {Object} [options] - an object with options.
* @param {'extended'|'basic'} [options.format='extended'] - if 'basic', hide delimiters between date and time values.
* @param {'complete'|'date'|'time'} [options.representation='complete'] - format date, time with local time zone, or both.
* @returns {String} the formatted date string (in local time zone)
* @throws {TypeError} 1 argument required
* @throws {RangeError} `date` must not be Invalid Date
* @throws {RangeError} `options.format` must be 'extended' or 'basic'
* @throws {RangeError} `options.representation` must be 'date', 'time' or 'complete'
*
* @example
* // Represent 18 September 2019 in ISO 8601 format (local time zone is UTC):
* const result = formatISO(new Date(2019, 8, 18, 19, 0, 52))
* //=> '2019-09-18T19:00:52Z'
*
* @example
* // Represent 18 September 2019 in ISO 8601, short format (local time zone is UTC):
* const result = formatISO(new Date(2019, 8, 18, 19, 0, 52), { format: 'basic' })
* //=> '20190918T190052'
*
* @example
* // Represent 18 September 2019 in ISO 8601 format, date only:
* const result = formatISO(new Date(2019, 8, 18, 19, 0, 52), { representation: 'date' })
* //=> '2019-09-18'
*
* @example
* // Represent 18 September 2019 in ISO 8601 format, time only (local time zone is UTC):
* const result = formatISO(new Date(2019, 8, 18, 19, 0, 52), { representation: 'time' })
* //=> '19:00:52Z'
