Camera module should base connections on the port number rather than serial number

[TrentHouliston]

Swapping camera parts at RoboCup is difficult as when we do we need to change the serial numbers in the configuration.
Instead, we should scan which cameras are connected and find some way to assign them left/right based on which USB port they are attached to.

Would require actually having the cameras plugged into the left and right port 😛 Would be much more convenient if you could look for the nose or do some calibration at startup to determine left and rightness based on an image
