* feat: comparators for annotation target equality
- Adds `addTargetComparator()` to the Annotation API, allowing plugins to define additional comparators for certain annotation types.
- Update usage of `_.isEqual()` for targets to use the `areAnnotationTargetsEqual()` method, which uses any additional comparators before falling back to a deep equality check.
- Handle aborted `getAnnotations()` calls gracefully in the AnnotationInspectorView
* test: add unit tests for target comparators
