DiffBIR Stage 2 / IRControlNet support?

[Splendide-Imaginarius]

DiffBIR appears to use ControlNet models as its stage-2 models. (It's using SD 2.1; the ControlNet models appear to be conceptually similar to the Tile models.) It would be nice if sd-webui-controlnet added support for those models. The model weights are linked here. Currently the DiffBIR models raise this exception:

sd-webui-controlnet/scripts/controlnet_model_guess.py

Line 292 in 56cec5b

raise Exception('[ControlNet Error] Cannot recognize the ControlModel!')

If there's some documentation you can point me to regarding adding support for new model types, I don't mind giving it an attempt myself.
