Update lama-cleaner/iopaint

[d8ahazard]

Lama-cleaner has been updated and replaced with "iopaint".

Thank you for your contribution to the code. I have reviewed IOPaint, but as it is still in Beta release, I would like to wait for any fixes until the official release. What do you think?

I strongly recommend making this update. We have encountered multiple issues due tu lama_cleaner which is forcing to use diffusers<=1.16.0

Please take a look, I hope this gets approved, as we had to remove the ext.
Sanster/IOPaint#436

I have verified the official release of IOPaint and will approve the pull request shortly.

I will hold off on merging due to the following error that occurred while importing the iopaint package:

      File "/stable-diffusion-webui/venv/lib/python3.11/site-packages/iopaint/schema.py", line 16, in <module>
