    Description

      Before writing "deflated" data to output stream, check if the compressed size of a zip archive entry is bigger than or equal to its original size, if so then use method "stored" instead, just like what 7-Zip does when creating a zip file.

      The optimization above can be done by
      1. adding a new option "DEFLATED_IF_NECESSARY" for ZipArchiveOutputStream#method.
      2. auto-selecting final method(DEFLATED or STORED) if DEFLATED_IF_NECESSARY specified.
