Write basic logic and speed test for the "21+3" and "Perfect Pairs" side bets in blackjack.

Currently, one run to analyze a full 8-deck shoe for "Perfect Pairs" EV takes like 0.04 seconds.

Analyzing the same amount of cards for the "21+3" side bet takes roughly 45 seconds. This is unacceptable.

I suspect the time suck is the logic to tell whether there's a straight in the hand. It involves making like 9 or more permutations of a string, and does that for every permutation of 3 cards from the shoe, so you can see how this gets slow.

Refactor the analysis of straights to cut down runtime. Thinking of picking one card, seeing whether there's a predecessor or successor card also in the hand, then checking if the final card is the next spot.

Make sure this works and runs through the default 12 shoes.

Eventually blackjack.py will need to be split out as the file is getting a little monstrous.

But, for now, merge the code from pp_plus3.py into blackjack.py and delete that file. We'll implement timing/benchmarking into normal blackjack execution at a later point.

Move applicable code from private casino project into this repo.
