Bug: fix blank 2B field in SPADV deck.

The following field need to be fixed in [decks/SPADV/cards.csv](https://github.com/ButteredGroove/fac-flipper/blob/main/decks/SPADV/cards.csv):

Row 3 Col RADV 2b: change from blank to 2 - it's that way because it's the only card with multiple fields for doubles.
