More stable communication

[ysims]

nugus_controller provides us with a way to communicate between NUbots and Webots without having to use the RoboCup official controller where GameController and AutoReferee can get in the way of testing systems.

However, the communication code on the NUWebots side is unstable. We would like it to be stable so we can reliably use it.

This is noticed while running scripttuner with the nugus_controller. Most of the time it crashes in the first 10 seconds. Occasionally, it will run nicely and not crash. Ideally it runs nicely and doesn't crash, otherwise it makes it very hard to test things and tune scripts.

Works fine now with the robocup player controller code.
