 * @name parseISO
 * @category Common Helpers
 * @summary Parse ISO string
 *
 * @description
 * Parse the given string in ISO 8601 format and return an instance of Date.
 *
 * Function accepts complete ISO 8601 formats as well as partial implementations.
 * ISO 8601: http://en.wikipedia.org/wiki/ISO_8601
 *
 * If the argument isn't a string, the function cannot parse the string or
 * the values are invalid, it returns Invalid Date.
 *
 * @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).
 * @typeParam ResultDate - The result `Date` type, it is the type returned from the context function if it is passed, or inferred from the arguments.
 *
 * @param argument - The value to convert
 * @param options - An object with options
 *
 * @returns The parsed date in the local time zone
 *
 * @example
 * // Convert string '2014-02-11T11:30:30' to date:
 * const result = parseISO('2014-02-11T11:30:30')
 * //=> Tue Feb 11 2014 11:30:30
 *
 * @example
 * // Convert string '+02014101' to date,
 * // if the additional number of digits in the extended year format is 1:
 * const result = parseISO('+02014101', { additionalDigits: 1 })
 * //=> Fri Apr 11 2014 00:00:00
