zip files

   I just pushed the code of adding support for splitted zip in `ZipArchiveInputStream`.
   I didn't change much. Just skip the markers here
   [ if (sig.equals(ZipLong.DD_SIG)) {](https://github.com/apache/commons-compress/blob/205876d6f9eb60ac31f3ec848b23d025f32995ab/src/main/java/org/apache/commons/compress/archivers/zip/ZipArchiveInputStream.java#L370)
   
   Sample code:
   ```
   File lastFile = getFile("COMPRESS-477/split_zip_created_by_zip/split_zip_created_by_zip_zip64.zip");
   // build the input stream by just concatenating the splitted zips together
   SeekableByteChannel channel = ZipSplitReadOnlySeekableByteChannel.buildFromLastSplitSegment(lastFile);
   InputStream inputStream = Channels.newInputStream(channel);
   ZipArchiveInputStream splitInputStream = new ZipArchiveInputStream(inputStream);
   
   ArchiveEntry entry;
   while((entry = splitInputStream.getNextEntry()) != null) {
       // read from ZipArchiveInputStream
       ...
   }
   ```
