code: @Override
    public Result decode(BinaryBitmap image) throws NotFoundException {
      setHints(null);
      return decodeInternal(image);
    }
docs: This version of decode honors the intent of Reader.decode(BinaryBitmap) in that it
  passes null as a hint to the decoders. However, that makes it inefficient to call repeatedly.
  Use setHints() followed by decodeWithState() for continuous scan applications.
  
  @param image The pixel data to decode
  @return The contents of the image
  @throws NotFoundException Any errors which occurred
