99helpers sample ZIP64 archive

Small, but written in ZIP64 form (zip -fz): every entry has a ZIP64 extra field,
and the archive ends with a ZIP64 end of central directory record and locator.
The classic end record's central directory offset is set to FFFFFFFF, so a reader
that doesn't understand ZIP64 can't find the central directory.
