Simple Fast Chroma

Simple accelerated Chroma workflow utilizing a Hyper lora for 16-step functioning with minimal loss of quality and an optional second step. approx 1 minute for the first step, 1m20s for the second on an A4000 (Second step is bypassed by default, select the 2nd pass nodes/group and press b to enable).

Tested with Chroma v29.5 fp8 and FLAN-T5XXL-fp8. You will need the Hyper Chroma low Step Lora saved to your loras folder. Check out the same profile on the huggingface link for other acceleration loras, but this is the one I've settled on.

Mostly comfy core nodes but Uses CR Upscale from ComfyRoll custom nodes for the upscaling step if enabled.
