🚨 Anti-bot ideas 🚨

To mitigate the current bot situation, I propose the following changes:

• Add a captcha before starting the game. Once the captcha is solved, the frontend can pass the hash to the backend on the HTTP request that opens the websocket (101 switching protocols) and the server can validate it.
  

• Remove all planes that are stuck in the air at the same position for longer than 5 seconds. Consider a different logic for planes stuck on the ground.

• Only allow 1 plane to be updated for each IP address. Optional if Captcha is implemented, as it could break the game for players with VPN software.
