Possible bug in degradation_bsrgan

[DanilKonon]

It is possible that dimensions are permutated in the cropping operation in degradation_bsrgan_plus, degradation_bsrgan functions in 541, 450 lines.

It should be
img = img.copy()[:h1 - h1 % sf, :w1 - w1 % sf, ...] # mod crop
instead of
img = img.copy()[:w1 - w1 % sf, :h1 - h1 % sf, ...] # mod crop

I have the same question.

I think this is bug. I also change the code to use degradation model
