InstantX ControlNet Canny built for Flux not working.

Nobody has claimed this yet.

A ControlNet Model that is currently not working with Flux in Forge:

An error message shows:

`Recognizing Control Model failed: C:\Forge\stable-diffusion-webui-forge\models\ControlNet\InstantXFLUX.1-dev-Controlnet-Canny.safetensors

Thank you for all your work on Forge, It seems like a huge undertaking but with the steps you've taken, I'm super excited for it's future :)

Start with extensions-builtin/sd_forge_controlnet/scripts/controlnet.py, especially the model-processing paths at lines 414 and 554, and reproduce the reported failure with the InstantX FLUX.1-dev-Controlnet-Canny.safetensors model. Done means the ControlNet model is recognized without the shown AssertionError and can be used with Flux.
