napari plugin engine

napari-plugin-engine is a fork of pluggy, modified by the napari team.

There are some API and feature changes, including:

• discovery via naming convention as well as entry_points
• support for reordering of hook calls after registration.
• enhanced API for retrieving plugin package metadata.
• modified plugin call and registration exception handling
• modified HookResult object and hook call loop, with ability to retrieve the HookImplementation responsible for the result.
• lazy plugin discovery
• some changes to variable and attribute naming
• removed all deprecated code
• type annotations on everything
• pytest fixtures for testing
• a couple napari-specific convenience imports
