## Description of change
This implements a seperate ICCA card workflow for the slotted readers
acting how Resort Anthem expects, enabling cards to be inserted.
Additionally this fixes a bug where both card units would be treated the
same (for keypad reads) under Resort Anthem.
The slotted reader workflow was implemented as a seperate function for
two reasons - it would be nice to not mess with any existing code to
avoid breaking all the functional games, and the way the slotted readers
are handled by RA seemed different enough to how everything was already
designed to where it didn't make sense to keep adding special edge cases
for RA.
## Testing
IIDX18 was tested and cards could be inserted on both P1 and P2 side.
IIDX19 through 22 was tested to make sure nothing had broken for
wavepass emulation.
## Known Issues
In IIDX18, when a card isn't set but the insert key is pressed, after
the card timeout the game will error out with an invalid state error.
