ComfyUI Segment Anything

This project is a ComfyUI version of [a/sd-webui-segment-anything](https://github.com/continue-revolution/sd-webui-segment-anything). At present, only the most core functionalities have been implemented. I would like to express my gratitude to [a/continue-revolution](https://github.com/continue-revolution) for their preceding work on which this is based.
