📄 Description

Add SpriteSheetExtractor custom node

Adds two nodes for extracting sprite sheets from WAN (or any batch) video output:

SpriteSheetExtractor — Samples evenly-spaced frames, removes background via per-frame YCbCr chroma keying with flood-fill, applies palette lock for colour drift correction, and saves a horizontal RGBA sprite sheet PNG. Includes an interactive "Tweak Tolerance" panel for live adjustment without re-running generation.
SpriteSheetPreview — Displays the sprite sheet as a looping pixel-art animation with checkerboard background for transparent areas.

Details:

install_type: git-clone
No extra pip dependencies (uses PyTorch, numpy, Pillow — all ComfyUI built-ins)
NODE_CLASS_MAPPINGS: SpriteSheetExtractor, SpriteSheetPreview
Category: image/animation
