Double timestamps on debug log lines

[gavanderhoorn]

After merging #61, we now have double timestamps on debug logger lines:

[2023-07-14 14:42:07.146661] [192.168.255.1:64288]: FRI 2023-07-14 13:44:53.967 Attempting ...

We should probably remove the stamp prefixed by the debug logger .py.

Or perhaps preprocess the message received from MotoROS2, extract the on-controller timestamp and then print it as part of the debug logger output (ie: replace the timestamp in the first 'column' with the one received from the controller).
