Detection on lightnet 1.1.1 and brambox 3.0.0

Hello. First of all, thanks for this library it looks great.

I have been trying to run something similar to example/basic/detect.py to do detection on my dataset.

I get this error when using the file as it is File "./bin/detect.py", line 13, in <module> import brambox.boxes as bbb ModuleNotFoundError: No module named 'brambox.boxes'

I would rather not have to revert to an older version of brambox. I have not been able to find a way to do this with the current version.
