Instant ID SDXL

https://github.com/InstantID/InstantID

Instant ID uses a combination of ControlNet and IP-Adapter to control the facial features in the diffusion process. One unique design for Instant ID is that it passes facial embedding from IP-Adapter projection as crossattn input to the ControlNet unet. Normally the crossattn input to the ControlNet unet is prompt's text embedding.
