Conversion of PIL Image to NumPy fails when image has zero size

[vadimkantorov]

from PIL import Image
import numpy as np

a = np.empty((496, 0), dtype=np.uint8)
b = Image.fromarray(a) # succeeds
c = np.asarray(b) # fails with  SystemError: tile cannot extend outside image

PIL version: 8.4.0
NumPy version: 1.21.2

I can reproduce with Pillow 9.0.0 but no error with current main:

Oh, that's a good news. Please feel free to close this issue!
