Padim object has not attribute 'results'

[mathephysicist]

Describe the bug
If you modify padim/config.yaml save_to_csv to True you get an error

Expected behavior
I believe I should get a csv with the F1/AUROC scores?

Additional context
I built my environment following the steps provided.

@mathephysicist, it's probably because save_to_csv callback has not been maintained for a while. PadimLightning model had results attributes previously, but was then replaced. The callback needs to be updated accordingly to support the new design.
