Update atlas, template, and hashes.

Create a new jointfusion atlas from OASIS-TRT-20 brains registered to MNI152 via OASIS-30 Atropos template,
using newest antsRegistration and Atropos in antsCorticalThickness.sh.

Use OASIS-30_Atropos_template.nii.gz instead of OASIS-TRT-20 buildtemplateparallel.sh-constructed template,
to take advantage of the segmentations.
