      Description

      We need to interpolate the aperture correction to the position of every source, and apply this correction to all appropriate fluxes.

      The HSC implementation of this work (as well as that of DM-435) was done on issue HSC-191:
      https://hsc-jira.astro.princeton.edu/jira/browse/HSC-191
      There were changes to many packages, but the relevant ones for LSST are:
      https://github.com/HyperSuprime-Cam/afw/commit/057fb3c0581c512d5664f1883a72da950c9eae9d
      https://github.com/HyperSuprime-Cam/meas_algorithms/compare/HSC-3.0.0...u/jbosch/DM-191
      https://github.com/HyperSuprime-Cam/pipe_tasks/compare/4c3a53e7238cbe9...u/jbosch/DM-191

      Note that on the LSST side, we'll want to apply the aperture corrections either within a new plugin in meas_base or as a new part of BaseMeasurementTask, not as a change to the CorrectFluxes algorithm (which will be removed in the future along with the rest of the old measurement framework in meas_algorithms).
