COMPRESS-381 - improve performance by buffering

  Same goes for Compressor. Compressor streams are: bz2, gz, lzma, xz, pack200, 
Z.
  
  === Compressing a file ===
-       {{{final OutputStream out = new FileOutputStream(output);
+       {{{final OutputStream out = new BufferedOutputStream(new 
FileOutputStream(output));
        CompressorOutputStream cos = new 
CompressorStreamFactory().createCompressorOutputStream("bzip2", out);
        IOUtils.copy(new FileInputStream(input), cos);
        cos.close();}}}
  
  === Decompressing a file ===
-       {{{final InputStream is = new FileInputStream(input);
+       {{{final InputStream is = new BufferedInputStream(new 
FileInputStream(input));
          CompressorInputStream in = new 
CompressorStreamFactory().createCompressorInputStream("bzip2", is);
          IOUtils.copy(in, new FileOutputStream(output));
        in.close();}}}
