Wrapper around (de)serializing an epoch.json file. Although the underlying implementation is fairly straightforward, we extract this into a library so that the library serves as the “source of truth” for all valid epoch.json formats. Currently, there is only one format documented in RFC-0071. If we add a new format (e.g. change the version field) in the future, this library will ensure that all clients are aligned on format changes.
