Implement a Diffusers-compatible pipeline for the First-Last-Frame-to-Video (FLF2V) task. This allows users to generate videos given a first and last frame + prompt using the standard diffusers library interface and schedulers, fulfilling the Todo item: "Wan2.1 First-Last-Frame-to-Video > Diffusers integration".
This pipeline will:
Load the WanModel
Accept first_frame (image), last_frame (image), and prompt (text) as inputs.
Encode the images and text.
Run the diffusion loop using diffusers schedulers (e.g., UniPCMultistepScheduler as used in T2V example).
Decode the result into video frames.
