Issue DM-1943: HSC backport: convert Peak to PeakRecord
This issue covers transferring all changesets from [HSC-1074|https://hsc-jira.astro.princeton.edu/jira/browse/HSC-1074] and its subtasks, as well as: - An RFC to propose the API change, and any requested modifications generated by the RFC. - Additional fixes to downstream code that's broken by this change (HSC-side changesets should be present for most of downstream fixes, but perhaps not all).
