support Infinity

The model is fast and of high quality. Would you consider supporting it?

Review the linked Infinity repository and compare its model requirements with diffusers' existing integration patterns. The issue names no diffusers file, test, or entry point and does not define acceptance criteria, so the integration scope and a concrete definition of done must be established before implementation.
