Issue DM-6258: Improve detail for DRP object characterization in LDM-151
Includes coadd measurement, multifit, and forced photometry. Could be faster to write than other sections because we can lift from "blended-measurement" document that already exists in LDM-151 repo; could be harder because that document has already exposed a number of unresolved questions that may need to be addressed (by at least getting agreement among pundits on the best-bet approaches) before we can plan.
