title: SSZipArchive: Get filename of file being moved in one of the delegate methods (e.g zipArchiveShouldUnzipFileAtIndex)
body: <p>I have a zip file that I'm going to unzip using <code>SSZipArchive</code>. But I don't want to unzip every file in the zip. I need only some of the file based on condition.</p>
  
  <p>I know the delegate method of <code>SSZipArchive</code>, i.e <code>zipArchiveShouldUnzipFileAtIndex(fileIndex:, totalFiles:, archivePath:, fileInfo:)</code> will be helpful.</p>
  
  <p>But how can I get the name of the file being unzipped (being moved from zip file to the unzip location), so that I can return <code>true</code> or <code>false</code> using the condition ?</p>
