-| open-file -> This opens the file of the provided `file/path.mrc`-path.
-| as-lines - This reads the file by lines.
-| decode-marc21 -> This decodes the data as binary marc21 into an internal format.
-| fix(FLUX_DIR + "fix-marc21.fix")  -> This executes the provided Fix-transformation.
-| encode-json(prettyPrinting="true") -> This encodes the transformed data as JSON-Format.
-| write("stdout") -> This writes the Json-Data to standard output.
