From Cedric Pinson, "Here a fix about a leak in InputStream::decompress

I changed
       _in->setStream( new std::stringstream(data) );
to
       _dataDecompress = new std::stringstream(data);
       _in->setStream( _dataDecompress );

Then when the destructor is of InputStream is called I delete the
dataDecompress stringstream.
