remaining files after tests

Hello, while preparing the Debian package of nabu, I found this in the package

-rw-r--r-- root/root   2692096 2024-06-26 15:13 ./usr/lib/python3/dist-packages/debug.hdf5
-rw-r--r-- root/root    232448 2024-06-26 15:13 ./usr/lib/python3/dist-packages/input.h5
-rw-r--r-- root/root    232448 2024-06-26 15:13 ./usr/lib/python3/dist-packages/output.h5

it seems that the test are producing files which are not removed.

Cheers
