Issue DM-2980: refactor coaddition code
The HSC fork has coaddition code in two places: pipe_tasks and hscPipe. The code in hscPipe is what we use (though that depends on the code in pipe_tasks in places), while the code in pipe_tasks is more similar to what's currently on the LSST side. We want to bring the refactored version in hscPipe back to LSST, but we want to put it directly in pipe_tasks to remove the code duplication that currently exists on the HSC side. Work on this issue should begin with an RFC that details the proposed changes. Note that this should not bring over the "safe coadd clipping" code, which is DM-2915.
