Add AnnotationDifferentiator

[VeraPrinsen]

Fixes #608

Differentiating archetypes does not yet differentiate the annotations, resulting in all annotations of the parents being in the child archetype.

With this AnnotationDifferentiator, the entries in the annotations that are also in the parent are now removed from the annotations in the child archetype.
