img2img not working

[InformEthics]

Thank you for doing this great project!
using mlx-FLUX.1-schnell-4bit-quantized model and providing a --image-path argument the img2img function does not work. Output image is the same as input image:

diffusionkit-cli --prompt "Hand drawn illustration of a boy reading for his teddy bear sitting on a treehouse, the boy is wearing a hat with bear ears, a scarf, and rainboots, next to him is a bookshelf with books on it, in the background it is raining, autumn colours." --image-path ~/Desktop/sketch.png --model-version argmaxinc/mlx-FLUX.1-schnell-4bit-quantized --denoise 0.5 --height 1360 --width 768 --step 4 --output ~/Desktop/test2.png
