      Description

      First batch of code in the re-implementation of the zogy algorithm. Main features:

      • Using one PSF image for each exposure, but separate calculable values that will be re-used for the grid calculation.
      • Calculation of D, F_D, Varplane(D)
      • Calculation of S, Varplane(S)
      • Unit test to verify DFT convention.

            Would you please review this first version of the new zogy?

            At a few places, I refer to DM-25174 that is a technical note to be drafted soon. As this document does not exist yet, feel free to ask about details if you need background information for the review. Thanks.

            Please see my comments on the ip_diffim and pipe_tasks pull requests. I did not review the code in lsst-dm/diffimTests because it appeared to be tests supporting your development, but I can review it as well if you'd like.
