Resample morphometry into surface template spaces

[effigies]

Is your feature request related to a problem? Please describe.

In Neurostars #19517, some users expected to find morphometry data resampled into template spaces. This should be doable with little difficulty.

We should collect a list of desirable derivatives.

The issue that prompted my Neurostars post was that we expected to find the following files in template space, fsaverage6, in our case, because we specified --output-spaces fsaverage6

• lh.curve, rh.curv
• lh.sulc, rh.sulc
• lh.thickness, rh.thickness

Though I can see applications for the rest of the files in the surf directory, too. If this feature will be implemented, I'd also like to make sure that the data are resampled to any surface space provided (eg, fslr) and no only freesurfer-specific surfaces.
