Is it better to handle for the case num = int(line.strip()) = 0?

Hi thanks for sharing code.
if num = 0 https://github.com/faciallab/FaceDetector/blob/5b588f58884086d005a5ac67bd39a03ce631f8f4/mtcnn/datasets/wider_face.py#L43, for example
10422 0--Parade/0_Parade_Parade_0_452.jpg
10423 0
10424 0 0 0 0 0 0 0 0 0 0
10425 0--Parade/0_Parade_Parade_0_630.jpg
then, current_num != num, so flag still be 2. If so, in the next iteration the for line in f: will start from elif flag == 2:, but the current line 0--Parade/0_Parade_Parade_0_630.jpg (flag should be 0)

Is there any case that there is no bbox in a image? If so, I will handle this case.

Could you please send me a pull request to handle this problem?
