Secure the data sent from client

[shivangg]

Currently, any client can send the data to any pacman. Client 2 has access to the playerId of pacman 1 . Client 2 can change the direction of client-1's pacman by sending its playerId through updateNewDirection({playerId, direction})

An approaches to solve this issue:
Send the user JWT instead of playerId given to the server with updateNewDirection(). On the server that JWT maps to the correct playerId and updates that pacman direction. Now, the client 2 cannot update client 1 pacman.

Server will need to store the 2 user's JWT for each room.
