feat: CoAdapter

There're CoAdapter(Composable Adapter) models.

> We introduce CoAdapter (Composable Adapter) by jointly training T2I-Adapters and an extra fuser. The fuser allows different adapters with various conditions to be aware of each other and synergize to achieve more powerful composability, especially the combination of element-level style and other structural information.

There's a feature request from sd-webui-controlnet as well.

https://github.com/Mikubill/sd-webui-controlnet/issues/614

I hope ComfyUI also support it.

How do you think?

Thanks :)
