We have many hand-written String() methods (and similar) for enums. These require more maintenance and are more error-prone than using automatically generated methods. In addition, the auto-generated versions can be more efficient. Here, we switch to using https://github.com/loggerhead/enumer, itself a fork of https://github.com/diegostamigni/enumer, no longer maintained, and a fork of the mostly standard tool https://pkg.go.dev/golang.org/x/tools/cmd/stringer. We use this fork of enumer for Go 1.20+ compatibility and because we require the `-transform` flag to be able to generate constants that match our current code base. Some enums were not targeted for this change:
