(random-shuffle-idx items)Returns a random shuffle index for items.
items parameter is either a number of items or a coll of items
the-random argument is an instance of java.util.Random you want to use/reuse, if not provided a new (SecureRandom/getInstanceStrong) will be used, which is rather slow. (8 us per call vs 0.25us per call if you reuse a secure random).
Returned is the sequential number of shuffle. Use the number to shuffle the items.
