Using Stable Diffision models for Colorization

Willing to use Qwen-IE to color B&W pictures it is very important to use an appropriate prompt, the best that I found till now is the following: "Colorize this image, natural colors. Strictly preserve all shapes, edges and background details."

By using only python code, and adding some optimization trick, I was able to lower the coloring speed from 22 sec/image (ComfyUI) to 4 sec/image (Python only). So the speed now is not really an issue. I decided to no release an HAVC extension with  Qwen-iE because the HW requirements to get this speed are very high (RTX 5070TI and 64 GB RAM). If in the future will be released a DiT model with lower HW requirements able to color to a speed of 4 sec/image or better, I will evaluate the possibility to add it to HAVC.
