Viesus Cloud 1.1

• Runs Viesus 10 + X library
• Added AI Upscaling
  Upscaling factors: The resolution of the image is scaled up by the selected scaling factor. For example, a photo of 500w/px at 500h/px becomes 2000w/px and 2000h/px when scaled up by a factor of 4. The AI Upscaling functionality does not use conventional upsampling method, but Super Resolution (deep learning method). This ensures sharper results when upscaling an image, with conventional upsampling method an image may become blurry or pixelated.
• Added AI Artifacts Detection & Removal
  Auto: Viesus detects whether JPEG compression artifacts are present in the image and we remove the artifacts from the image.
  Enforce: Viesus always remove artifacts even if they are not necessarily JPEG artifacts.
