 * Returns the cartesian product of one or more iterables.

 * Based on https://stackoverflow.com/a/72059390
 *
 * @example
 * Consider the standard playing card ranks and its suits:
 * cartesianProduct([A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2], [♠, ♥, ♦, ♣]);
 * The product of these iterables would be [[A, ♠], [A, ♥]...] and so on until we have all 52 cards.
