Review Comment:
> This is public because callers would need to separately write/read the
FSTMetadata some their sources? The FST bytes can stream append only to disk,
but the end, the compiler produces the final FSTMetadata which must then be
stored somewhere?
Yes, users can either save the metadata to disk, or get the metadata object
directly. There is a way that does not require this: embed the metadata to the
end of the FST bytes, but that would be a bit too radical?
