scripts.inference_ig2mv_sdxl do not support imagetotetxure generation

[StepInfinite]

Hi, dear authors, thanks for the nice work.
Although the readme has provide the example to generate texture from image, the code scripts.inference_ig2mv_sdxl just support image to multi-view but not image to texture.
I am looking forward the author can provide comprehensive feature of scripts.inference_ig2mv_sdxl.
