Subject: [PATCH] deck: Implement unique identification of cards by assigning
 an id to each card Created an id as card-type-color-value To uniquely
 identify the same type color value card, I have also created a sameCardCount
 array that will to uniquely identify these card Finnaly created a unique id
 card-type-color-value-sameCardCount[id] Changed id typed to String in
 types.d.ts
