Support for new Sana 4k BF16?

[EnragedAntelope]

https://huggingface.co/Efficient-Large-Model/Sana_1600M_4Kpx_BF16 is now available, trying to find Comfy support for it. I see there is a PR for other Sana models so not sure if support for this could be incorporated there?

Hey AJO! Thanks. I don't expect great things, I guess if no one else wants then we don't have to press for incoporating it. I assumed (maybe wrongly) that it needs some sort of updated support to get the full capabilities out of it. I've seen some diffusers implementations that I think look a little better, but overall I still think it is < base SDXL quality, just very fast.
