530 series drivers are packaged use a Zstandard.

Filetype defines as "Zstandard compressed data (v0.8+)..." and and get an error when trying to install:

Unknown filetype "Zstandard compressed data (v0.8+), Dictionary ID: None" ?

Solution variant to add another option in unpacker.eclass, like:

                Zstandard*) 
                        "${exe[@]}" | tar --zstd --no-same-owner -xf - 
                        ;;
