Add data and commands for lesion-analysis tutorial (#21)

* Add new files: - t2_lesion/t2.nii.gz - T2w image with fake lesion - t2_sc_seg.nii.gz - SC segmentation generated using SCIsegV2 - t2_lesion_seg.nii.gz - lesion segmentation generated using SCIsegV2 * batch_single_subject.sh: Update with lesion-analysis * tutorial-datasets.csv: Update with lesion data
