When lycon.save 10000+ times, it occurs Fatal Python error: deallocating None

[ArsenLuca]

As title states

`
import lycon
from tqdm import tqdm
image_full_path = "00010640.jpg" # any image

for i in tqdm(range(20000)):
image = lycon.load(image_full_path)
image = lycon.resize(image, width=512, height=512, interpolation=lycon.Interpolation.LINEAR)
lycon.save("test.jpg", image)
`
It happens at about the 10344th iteration:

` 52%|██████████████████████████████████████████████████████████████████████████████████████▎ | 10344/20000 [01:06<00:56, 171.48it/s]Fatal Python error: deallocating None

But if I use cv2.imwrite instead of lycon.save, no such fatal error happened
