Issue DM-4879: Make coadd input catalogs contiguous
It's convenient if we can assume that coadd input catalogs are contiguous -- it simplifies the implementation of {{PropagateVisitFlagsTask}} (DM-4878), for example. Make it so. This is port of work carried out on [HSC-1293|https://hsc-jira.astro.princeton.edu/jira/browse/HSC-1293].
