[Broken, seeking fix] Hunyuan img2vid, LeapFusion, simple latent and denoise, 12GB VRAM

Based on https://civitai.com/models/1197557/hunyuan-i2v, but added blockswap and teacache for improved lower VRAM performance. And a Color Swap node to try and better match the source image.

I have only had luck by using a hunyuan motion LoRA in combination with the img2vid LoRA from LeapFusion. I hope to find better prompting techniques, and which LoRAs work well and which do not. Use extra weight on the LoRA trigger word if you have trouble getting it to work (for example, (8itchw4alk:1.4) for the Move Enhancer LoRA https://civitai.com/models/1186768/moveenhancer).
