A blackjack game which harnesses Zero Knowledge Proofs(ZKP) for proving the result each round.

counter_cnft.rs

This module defines the Counter cNFT object and provides methods to create and increment it.
The Counter cNFT is used as the VRF input for every game that a player plays.
The count always increases after use, ensuring a unique input for every game.
A player is required to create a Counter cNFT before playing their first game.
The UI can seemlessly create the Counter cNFT for the user by including the counter creation along with the game creation function in the same PTB.

• setup/createCounterObjectByPlayer: Creates a Counter cNFT object for the player. Should only run once if the player does not have a Counter cNFT object.
