Regional Condition Custom Node for Anima model

Created a comfyui custom node for Regional Conditioning for Anima model with the help of Codex. I think it works better than the sd forge couple -, but still have some downsides to it. Forge couple masks the text tokens which works for simple regions but fails for complex regions and and also does not follow the mask bounds very well. This custom node however masks both the text tokens as well as the image tokens so it does whatever forge couple does but with better bounds. But it also results in some uneven composition, so just have to play around with the parameters.
