Unlimited Wan video generation workflow with CreaPrompt

IMPORTANT: I'm currently investigating if bundling nodes into subgraphs may be causing the nodes to not operate in correct order. If I will conclude that is the case, I will upload an amended workflow.

This is a modified version of @zardozai's Unlimited Long Video Generation Loop (/model/1897323), but the Ollama part has been replaced with CreaPrompt, enabling you to define a prompt for reach segment of the generation by hand instead of relying on an LLM.
