Split napari-sparrow into sparrow (pipeline only) and napari-sparrow (plugin only)?

[SilverViking]

The sparrow pipeline is useful in itself, without the dependency on napari.

Should we split up the current napari-sparrow package into two packages, one perhaps called "sparrow" and containing only the pipeline itself, and "napari-sparrow" (which has "sparrow" as a dependency) with only the sparrow plugin code for napari?

I think the resulting two packages would be more focussed, and probably cleaner.

It was decided by the main sparrow authors to keep the pipeline and the plugin code together in a single repo.
