• This section will cover how the user can Hit or Stand during the game.
• At the start, it will give the user their first 2 cards, then it allows them to hit or stand
• We use a while loop to keep the choices running until they either bust or stand by breaking the loop
• If the user hits, they will get another card and that card's value will be added to the users score.
• The loop makes sure for every iteration, that the user score is not over 21
