What should this feature add?

Add a bypass option to the load lora node. So it can be disabled for an invocation without having to remove it from the node graph. This would be a short term hack to relieve a pain point some users are having with the node editor, as it is a long winded and a bit of a pain to wire and unwire a lora node. In the longer term either a global bypass or disable option on all nodes or some kind of sub node graph where adding removing and reordering loras is much simpler.

Here is a quick mockup I made with some code changes.

code changes to the LoraLoaderInvocation class in the model.py file

new bypass: bool input parameter to enable the bool toggle on th UI

        default=False,
        description="Bypass the lora and pass the unet and clip through unaltered")

Conditionally add the loara to the unet and clip depending on the bypass bool

            if self.bypass:
                output.unet = self.unet
            else:
                output.unet = copy.deepcopy(self.unet)
                output.unet.loras.append(
                    LoraInfo(
                        base_model=base_model,
                        model_name=lora_name,
                        model_type=ModelType.Lora,
                        submodel=None,
                        weight=self.weight,
                    )
                )

        if self.clip is not None:
            if self.bypass:
                output.clip = self.clip
            else:
                output.clip = copy.deepcopy(self.clip)
                output.clip.loras.append(
                    LoraInfo(
                        base_model=base_model,
                        model_name=lora_name,
                        model_type=ModelType.Lora,
                        submodel=None,
                        weight=self.weight,
                    )
                )

Would really appreciate having the bypass added to all nodes that may be bypassed.
