Browsers are dumb and let any website do requests to localhost this should
prevent this without breaking things. CORS prevents the javascript from
reading the response but they can still write it.

At the moment this is only enabled when the --enable-cors-header argument
is not used.

This change resolves an error when a node with OUTPUT_IS_LIST=(True,)
receives an ExecutionBlocker. I've also added a unit test for this case.

This isn't actually a lora format and is saving the full diff of the
weights in a format that can be used in the lora loader nodes.

text_encoder_diff should be connected to a CLIPMergeSubtract node.

model_diff and text_encoder_diff are optional inputs so you can create
model only loras, text encoder only loras or a lora that contains both.

This is a format with keys like:
text_encoders.clip_l.transformer.text_model.encoder.layers.9.self_attn.v_proj.lora_up.weight

Instead of waiting for me to add support for specific lora formats you can
convert your text encoder loras to this format instead.

If you want to see an example save a text encoder lora with the SaveLora
node with the commit right after this one.

As suggested by @ltdrdata, we can automatically consider nodes that take
the UNIQUE_ID hidden input to be NOT_IDEMPOTENT.
