Cropping image does not make sense for training 2D kernel

Lines 69 to 75 in 65da21c

	### Crop images
	Crop images and their respective mask in order to remove certain slices:
	~~~
	python ./utils/crop_image_and_mask.py --folder-path /path/to/folder/ --file-name file_name.nii.gz --first-slice XXX --last-slice XXX
	~~~

I understand the pertinence of this code when training the 3D model (ie: once the 2D model was trained), but the way it appears in the README suggests this script needs to be run before training the 2D model.

@plbenveniste is this a mis-placement of that section in the README?

Yes! It does look misplaced. I remember using this code on the 2D model prediction, so there might be a problem in the readme here
