Change indexing to make card ordering more intuitive
Update the indexing so that the table starts at "1". This way the ordered card layout (used for key generation) starts with the Ace of Diamonds and proceeds through the cards and suits as normal. This seems cleaner than awkwardly prepending the 10 of Spades. However, it involves a slight tweak to the key key_derive function to support the change in card order.
