�Funtions
randomnessRequest
function randomnessRequest(uint256 _seed, bytes memory _data) public returns (bytes32 reqId);
_seed : a random number provided by the caller
_data : the result of callbackAddress and callbackFunc after encoding
bytes memory data = abi.encode(address(this), this.fulfillRandomness.selector);
callbackAddress: smart contract address receive random number
callbackFunct : hen a function is called, the first 4 bytes of calldata specifies which function to call.
fulfillRandomness
function fulfillRandomness(bytes32 reqId, bytes calldata _data, uint8 v, bytes32 r, bytes32 s) external;
reqId: request id generated when calling function randomnessRequest
_data: includes callbackAddress and callbackFunc after encode
