        The zzip_dir_alloc_ext_io function allocates a new ZZIP_DIR handle and do basic initializations before
       usage by zzip_dir_fdopenzzip_dir_openzzip_file_open or through zzip_open (ext==null flags uses { ".zip"
       , ".ZIP" } ) (io ==null flags use of posix io defaults)

        The zzip_dir_alloc function is obsolete - it was generally used for implementation and exported to let
       other code build on it. It is now advised to use zzip_dir_alloc_ext_io now on explicitly, just set that
       second argument to zero to achieve the same functionality as the old style.
