Support napari>=0.5 (#274)

* Remove as_dict kwarg

* Pin to napari >= 0.5

* Fix scatter test?

* Update test image

* Fix brain data

* Fix another as_dict arg

* Fix FutureWarning

* Fix scatter test's OverflowError

And revert to original baseline images.

* Try updating mypy's python version.

* Revert shape → newshape and suppress deprecation warning.
