0.5.1

What's New:

• You can now save face models as "safetensors" files (stored in <sd-web-ui-folder>\models\reactor\faces) and load them into ReActor, keeping super lightweight face models of the faces you use
• "Face Mask Correction" option - if you encounter some pixelation around face contours, this option will be useful
• Fixes and improvements

Thanks @jiveabillion for adapting "Face Mask" solution taken from another excellent extension ototadana/sd-face-editor (thanks to @ototadana)
