Change lumbar file from full-body (t2.nii.gz) to lumbar region (t2_lumbar.nii.gz)

This removes the need for the user to perform a crop on the full-body image, and also minimizes ambiguity between this image and the other t2.nii.gz file.

See my comment in the gslide: i suggest to put it under its own folder to avoid conflicts with the generated segs, labels/ folders, etc.

cd ../t2_lumbar

I forgot to put this cd ../t2_lumbar command in the Course slides, though. So, thank you for catching this!
