[Bug]: Fails to load if control net is not installed. TypeError: '<' not supported between instances of 'NoneType' and 'int'

Is there an existing issue for this?

[X] I have searched the existing issues and checked the recent builds/commits of both this extension and the webui

Have you updated WebUI and this extension to the newest version?

[X] I have updated WebUI and this extension to the most up-to-date version

Do you understand that you should go to https://github.com/IDEA-Research/Grounded-Segment-Anything/issues if you cannot install GroundingDINO?

[X] My problem is not about installing GroundingDINO

What happened?

i tried to install this extension but it fails with this error

Traceback (most recent call last):
  File "X:\stable-diffusion-webui\modules\scripts.py", line 270, in wrap_call
    res = func(*args, **kwargs)
  File "X:\stable-diffusion-webui\extensions\sd-webui-segment-anything\scripts\sam.py", line 329, in ui
    priorize_sam_scripts(is_img2img)
  File "X:\stable-diffusion-webui\extensions\sd-webui-segment-anything\scripts\sam.py", line 304, in priorize_sam_scripts
    if cnet_idx < sam_idx:c
TypeError: '<' not supported between instances of 'NoneType' and 'int'`

When I look at it, it appears to fail on cnet_idx < sam_idx: and I believe that is because I don't have the control net extension installed so it fails because cnet_idx is None.

Steps to reproduce the problem

Don't have control net extension installed.
Install this sd-webui-segment-anything extension
Start the app, and view the error 'TypeError: '<' not supported between instances of 'NoneType' and 'int'`'

What should have happened?

The app should load and I should see this extension appear.

Commit where the problem happens

no

Console logs

Additional information

maybe you can initialize cnet_idx to a high number like 100000000 instead of None, then it wouldn't fail the comparison.
