When running sextractor / PSFex we get a PSF object with a certain format.
Other algorithms like ZOGY provide a simpler PSF result (often, this is just a single image of the PSF).
We should expand the PSF object to be able to use this information.
The use case (which is not urgent right now), is that a difference image from ZOGY will have a PSF that can be used downstream. Right now we don't use the PSF in the downstream of the difference image, so it doesn't really matter.
