Image size doesn't change

[MehediH]

Hi! Thank you for this awesome lib - it works really well. However, I noticed a minor issue - after removing the background, the image still has the same w x h - would it be possible to have an option so that the image size gets updated? Similar to how iOS Cutouts work in the Photos app, I'd expect the new image URI to have the updated size rather than the original size.

Thank you!
