* This method is like `zip` except that it accepts an array of grouped

* configuration.
*
* @since 1.2.0
* @category Array
* @param {Array} array The array of grouped elements to process.
* @returns {Array} Returns the new array of regrouped elements.
* @see unzipWith, zip, zipObject, zipObjectDeep, zipWith
* @example
*
* const zipped = zip(['a', 'b'], [1, 2], [true, false])
* // => [['a', 1, true], ['b', 2, false]]
*
* unzip(zipped)
* // => [['a', 'b'], [1, 2], [true, false]]
