return option min_vol_lesion

[ThoumyreStanislas]

Quick description

I've put the min_lesion_volume option back in because the script doesn't work without it and the problem is that if I remove the option, the compute_lesion_stats script in scilpy.utils.metrics_tools takes a default value of 7mm without being able to change it. so we'll just have to make sure for now that when we use this script after scil_label_from_mask.py we keep the same minimum volume between the two scripts.
