/**
 * @description
 * Transposes an array of arrays (e.g., the output of `zip`) so that the first array contains the first element of each input array, the second array contains the second element, and so on.
 * If the input arrays have different lengths, missing values are left as `undefined`.
 *
 * @param {T[][] | List<List<T>> | null | undefined} array The array of arrays to transpose.
 * @returns {T[][]} The transposed array.
 *
 * @example
 * unzip([[1, 2], ['a', 'b']]) // [[1, 'a'], [2, 'b']]
 * unzip([[1, 2], ['a']]) // [[1, 'a'], [2, undefined]]
 * unzip(null) // []
