Write a function called maximum_product, that finds the maximum possible product between two lists of integers. Save your function in a file called hw03_01.py. Your maximum_product function should take two input parameters representing two separate lists of integers and return the maximum possible product between one number from the first list and another number from the second list. The following example output demonstrates how the function might behave. If one of the lists or both lists are empty, the function should return None as the maximum product
