       remove sfeed "branding" in outputs
       
       Technically for sfeed_atom this violates the RFC standard. There must be an
       author in the feed or for an item. However sfeed is not the author, it is a
       generator.  All readers will read these feeds anyway.
       
       https://www.rfc-editor.org/rfc/rfc4287#section-4.1.1
       "atom:feed elements MUST contain one or more atom:author elements, unless all of
       the atom:feed element's child atom:entry elements contain at least one
       atom:author element." *shrug*
