IndexError in CLIPSetRegion

[qwitriy]

Hi!

In the CLIPSetRegion if target_text value starts or ends with space, python throws error: IndexError: too many indices for array: array is 1-dimensional, but 2 were indexed

Traceback (most recent call last):
  File "C:\Users\user\Documents\ComfyUI\execution.py", line 182, in execute
    executed += recursive_execute(self.server, prompt, self.outputs, x, extra_data)

I fixed it locally using strip() on target_text after this https://github.com/BlenderNeko/ComfyUI_Cutoff/blob/master/cutoff.py#L86 No sure if this quickfix in proper place.

Yeah that would probably be a smart thing to do for both region_text and target_text at the top of that function call. If you want you can put in a PR with the changes, or I'll push things once I get home.

Thank you. I made such edit. Please review.
