AutoClosing doesn't seem to remove tmp files. #235

Thank you so much for this library, it saved us alot of time. I have a small question however?

Using the example provided(code below) on the ReadMe.md and version 2.1.0 of the library. The stream closes but the tmp file still exists until you run 'workbook.close()'. Is this intentional? Should the autoclosable not do this on its own?

try (
  InputStream is = new FileInputStream(new File("/path/to/workbook.xlsx"));
  Workbook workbook = StreamingReader.builder()
          .rowCacheSize(100)
          .bufferSize(4096)
          .open(is)) {
  for (Sheet sheet : workbook){
    System.out.println(sheet.getSheetName());
    for (Row r : sheet) {
      for (Cell c : r) {
        System.out.println(c.getStringCellValue());
      }
    }
  }
}

It should, and I'm not sure why it wouldn't for you. The close() method is called by the try-with block; Autoclosable classes just have to implement that method.
