Support for Cellpose 4

[SebastienTs]

Any chance that cellpose-napari gets updated to fully support Cellpose 4?

In general Napari plugins meant for an underlying BIA library/tool are poorly maintained, or their compatibility with newer versions is poorly advertised. Some mechanism should be enforced to inform / warn the user.

Hey @SebastienTs -- I'm wondering this too. Have you heard anything about this?

[SebastienTs]

No, I believe that it is still not working as the plugin has not been updated in a long while. CP team probably focus on its own GUI.

Good news @leerberg26 and @SebastienTs: you can now use:
pip install git+https://github.com/jeskowagner/cellpose-napari.git@cellpose-v4

to install a version of this plugin that automatically detects your cellpose version (3 or 4) and exposes the right functionality automatically.

Note that if you are using cellpose v4 and want to use the diameter setting: after installing this plugin, also use (Edit: this is no longer required thanks for work in upstream)

pip install --no-deps git+https://github.com/jeskowagner/cellpose.git

to fix an issue in the current cellpose version related to the diameter affecting the mask output. I have submitted to both repositories (1, 2) to try and get these improvements merged 🎉

🔥 thank you @jeskowagner !! I will review this PR in a couple of weeks and merge it into the main repo. @leerberg26 and @SebastienTs if you test it that will be helpful too!
