Use of Deflate64 in decompression

[mserylak]

Hello,

When trying to decompress a zip file I got Error: unsupported Zip archive: Compression method not supported message. It seems that Deflate64 needs to be used to decompress this file. Could this compression method be added to ripunzip?

Thank you!
