npe2 conversion (napari plugin engine 2)

[GenevieveBuckley]

Migration to the new napari plugin engine 2 spec, see https://napari.org/stable/plugins/npe2_migration_guide.html#migrating-using-the-npe2-command-line-tool

For some reason it's not detecting that I merged #10, would you mind merging in main manually (or git rebasing on main) so only the relevant changes are visible?

[jni]

Can you also remove the napari-plugin-engine dependency, imports, and decorators? I think the convert script still assumes that one wants to support both npe1 and npe2, but that is definitely not the case anymore.

Done. Do I need to add npe2 to the requirements.txt file?

No, since we don't import from npe2!

We will need to add the yml to the manifest, but let me do that in a separate PR where I plan to update setup.py to pyproject.toml.

(Unless you want to do it here so it stays consistent...)

What do you prefer? (I did make an issue here about pyproject.toml #13)

I don't mind leaving it till the fix of #13. In we go! 😊
