      Description

      The old meas_extensions_ngmix tried to wrap ngmix functionality within the constraints of DM's existing SingleFrameMeasurement framework, which immediately rules out a lot of what ngmix does well (fitting multiple bands or epochs together).  It also never really got off the ground.

      Blow away the SFM plugins that currently exist, and replace them with (to start) a CmdLineTask that processes all bands in a patch at once, and loops over optionally-deblended objects without trying to package that up in some kind of plugin framework.  This task will depend on all current pipe_tasks multiband outputs (or at least deepCoadd_ref).

      Once we've gained some experience with the actual APIs of measurements like this have, we can consider factoring that out into a new measurement framework in e.g. obs_base.
