Make SwipeCard reusable?

Feels wasteful to have to recreate the views every time in cardForIndexAt. It would be super awesome to see card view reuse if possible!!

Loving everything else!

Thanks for the suggestion @disczteam. Are you seeing any performance issues? This would be a nice feature, however I do not really see the need for it.

For UITableView, we need cell reuse to maintain 60fps while scrolling. In the case of this library, we only ever have 2 cards on screen, so it seems like a wasted effort since we are at 60 fps most times anyways. The one potential spot for improvement is right after a card is swiped; there is currently a small delay at this point and card reuse could possibly reduce the delay
