Issue DM-2674: Get meas_mosaic working on HSC data with LSST stack
We have an old, bitrotted version of meas_mosaic on the LSST side, created in a failed attempt to get it running on LSST PhoSim data. Now that we're making a serious effort to get HSC data running through the LSST pipeline, we'll need to get it running with the LSST pipeline at least on HSC data, which will probably involve just merging everything from the HSC side over, and then fixing it until it builds and runs. For this issue, we'll assume that we're going to use the Eigen backend for the matrix solver, rather than the MKL one we use on the HSC side. That will make it much slower (since MKL is multithreaded and we can't make Eigen multithreaded for just meas_mosaic), but hopefully still usable.
