Image Outpainting - Vace + Wan 2.1

This is a modified version of kijai's vace video outpainting workflow from his WanVideoWrapper. This workflow uses an image as input instead of a video, and that image will be animated and outpainted. You can also add a reference image for the video generation and use a custom mask.

This is my first workflow and my goal was to recreate the "expand anything" example use case from the VACE paper, since I couldn't find a workflow for it.
