A bug when cropping images?

[yosider]

Hi, thank you for your great research!
I'm afraid I think there is a bug at the random_crop function in utils.py:

curl/utils.py

Lines 244 to 245 in 23b0880

	w1 = np.random.randint(0, crop_max, n)
	h1 = np.random.randint(0, crop_max, n)

I think the crop_max should be modified as crop_max + 1.
If left as it is, the bottom and rightmost columns of the image are not included in cropped_image. Also, an error occurs when output_size==img_size.
I'm sorry if I'm wrong :)
