Minor release to adjust ArtCNN_R8F64_Chroma_DN.
Changed:
- ArtCNN_R8F64_Chroma_DN: Denoising strength increased back to match the other DN and the JPEG models. This provides better reconstruction quality overall and does look better when fine detail isn't lost. The previous change was aimed at increasing the amount of fine detail retained, at the expense of reducing denoising strength which looked worse on a variety of shows.
