Add BIM-VFI Segment Interpolate node for bounded peak RAM

Processes numbered segments of the input batch so users can chain
multiple instances with Save nodes between them, freeing each segment's
output before the next starts. Model pass-through output forces
sequential execution via ComfyUI's dependency graph.
