The psf exp warp produces a variance 30% smaller.
All the same code is used, the main difference I see is that the psf image gets border that is masked
Note this doesn't affect the shear recovery in my tests, but we should figure it out
made a psf coadd that doesn't get any masking, still happens
fixed in latest descwl_coadd
