* Unzips an array of arrays, applying an `iteratee` function to regrouped elements.
*
* If the array is `null` or `undefined`, returns an empty array.

* @param array - The nested array to unzip. This is an array of arrays,
* where each inner array contains elements to be unzipped.
* @param iteratee - A function to transform the unzipped elements.
* @returns A new array of unzipped and transformed elements.
*
* @example
* const nestedArray = [[1, 2], [3, 4], [5, 6]];
* const result = unzipWith(nestedArray, (a, b, c) => a + b + c);
* console.log(result); // [9, 12]
