Cellpose integration

[pr4deepr]

PT-BIOP has a nice Fiji cellpose wrapper that calls cellpose from Fiji: https://github.com/BIOP/ijl-utilities-wrappers
Enable compatibility by allowing this as an option.
Points to consider:

• Instructions to install cellpose;

  • links to python environment config
  • video tutorial?

• Rescaling of image done in GAT for Stardist prediction. Determine the radius we pass to cellpose?

• Add test macro to test different options in Cellpose??

Bioimageio will have cellpose integrations soon without need for python environments
