Issue: [Bug] SCUNet: tiles are visible
Labels: bug-report

### Is there an existing issue for this?

- [X] I have searched the existing issues and checked the recent builds/commits

### What happened?

Denoise a picture with tiling enabled.

tile size: 256, overlap: 64

This is a side effect because SCUNet uses local and non-local properties.
Tiling is a non sense.

### Steps to reproduce the problem

1. Generate a noisy image or use attached
2. SCUNet, (upscale=1), set tile size and tile overlap
3. Denoise


### What should have happened?

In fact, this is due to the fact that the SCUNet algo uses local and non-local properties.
Tiling is a non sense for SCUNet: refer to the paper.
