Remove rate in game controller

[timonegk]

Proposed changes

This PR removes the rate from our game controller client. The rate limited the game controller message to 5 Hz leading to a growing message queue because the game controller publishes udp messages with 20 Hz. Receiving from the socket is blocking, therefore no queue is actually needed.

Necessary checks

• [ ] Update package version
• [ ] Run catkin build
• [ ] Write documentation
• [ ] Create issues for future work
• [x] Test on your machine
• [ ] Test on the robot
• [x] Put the PR on our Project board

You might want to add a minimal system sleep call.

No, as I said, recvfrom is blocking, no sleep is necessary.
