Inconsistent results between old and current versions of dnsmos_local.py

[sleglaive]

Hi,

I used to work with an older version of the dnsmos_local.py script, which uses the models stored in bak_ovr.onnx and sig.onnx, both still available in the DNSMOS folder.

However, this older version appears to produce results that differ significantly from the current version of the script, which now relies on the sig_bak_ovr.onnx model.
