Adaptive Cards Pool | A Pool of Card Caches

What

To show an example on how to implement a lookup pool of caches to prevent frequently re-rendering

How

1. Use two sets (as queues of unique elements) to record the MRU (most recently used) time of normal cards and stateful cards
   • Where the stateful cards is defined as those uses Input.* (detect with onInputValueChanged) or Action.ToggleVisibility (detect with onElementVisibilityChanged)
2. Use one object (cardPool) to store all the AdaptiveCards instances, and purge as needed
