several fields in dmarc and tls reports have known string values. we have a Go
string type for them. sherpats (through sherpadoc) turns those strings into
typescript enums, and sherpats generates runtime-typechecking code (to enforce
correct types for incoming json, to prevent failing deeper in the code when we
get invalid data (much harder to debug)). the Go not-really-enum types allow
other values, and real-world reports have unknown/unspecified/invalid values.
this uses the sherpadoc -rename flag to turn those enums into regular untyped
strings, so sherpats doesn't generate enum-enforcing runtime type checking
code.
this required an update to sherpadoc, to properly handling renaming a type to a
basic type instead of another named type.
