Warp both image and mask to label map space

[tashrifbillah]

This line loads the original mask:

TBSS/lib/skeletonize.py

Line 149 in 71d57f7

meanFAmaskData= load(args.templateMask).get_data()

It should be the warped mask when --space is different from --template.

Not only that, if --skeleton, --skeletonMask, --skeletonMaskDst, and --SEARCH_RULE_MASK are provided, they all should be warped!

[tashrifbillah]

But warping a --skeletonMaskDst is probably incorrect.

A more sane approach can be to raise an error if anything more than --template is provided for arbitrary label map based ROI analysis. Or the additional ones can be ignored silently with a warning message.
