feat: enhance Protocol18 and SocketWrapper for improved functionality

- Added support for the new world border hit flag in Protocol18 for protocol version 1.21.2.
- Updated SocketWrapper to throw a SocketException if SendDataRAW is called when not connected, improving error handling.

These changes enhance the protocol handling and error management in the Minecraft Console Client.
