Can we add some tests for maps warping? We have 0 coverage on the warpers.

Can we add some tests for maps warping? We have 0 coverage on the warpers.

We have similar coverage reporting structure as the parcellations. There's a test for template space warping via ANTs and the native one takes way too much time (hence we didn't have it for parcellation as well). For the FSL one, it only does native space warping, so we don't have a test for that as well.
