Description
In DM-10805 we fixed instances where the PSF dimensions between the two images were mismatched, however, this (often) leads to cases where the resized PSFs don't have the same center – in this case, the cross-convolved (PSF matched) images will be offset and the subtraction will be bad.
This situation happens when the PSF of the template has been warped or is the result of a coadd.
This needs to be fixed in this ticket.

A preliminary attempt to fix this has been made by finding the brightest pixel in each PSF and offsetting one or the other until their brightest pixels have the same coordinate.
