Feature: Add basic progress indicator & activity info

[psobolewskiPhD]

This is a basic attempt at addressing #27
and showing some status/busy info the napari gui.
The potentially long running tasks will now show an indicator that something is happening (the neato moving boxes in the lower right)
Additionally, a notification is provided of the main tasks after click run: (down)loading models and running segmentation

Test fails seem to be due to: napari/napari#4747 (comment)
Maybe should just drop python 3.7 tests? and add linux?

Maybe should just drop python 3.7 tests? and add linux?

I can't see the direct connection to the importlib-metadata issue mentioned in that comment, but yes, if we're not explicitly pinning the napari dependency here to v0.14.4 (the last one to support 3.7), then i wouldn't expect any tests to work on 3.7. go ahead and drop

[psobolewskiPhD]

Hi @tlambert03 the python 3.7 tests are actually running in napari 0.4.14, but failing due to the importlib_metadata issue. Anyhow, I will make a separate PR to try to try to drop 3.7 and add linux? I can probably copy-pasta from the cookiecutter 😉

[psobolewskiPhD]

Hmm, so now it's the same symptom as napari-serialcellpose with macOS tests stalling:
guiwitz/napari-serialcellpose#8
Not sure why simply adding progress=True would do that...

Edit: The tests hang for my locally too, even though everything works when run in napari, so it's something related to qtbot/pytest-qt?

[psobolewskiPhD]

Grr, the hanging tests.
Happens locally on my mac too -- but everything works when running in napari.
