Issue

This PR is a follow-up of the #374. I faced the issue with using a TextAnnotator<W3CTextAnnotation> with the useAnnotator:

That's because:

the TextAnnotationStore doesn't fully extend the Store type: https://github.com/recogito/text-annotator-js/blob/bd9e75cd682b809c54c46a3b78bf8bcaeff4a3b2/packages/text-annotator/src/state/TextAnnotationStore.ts#L4-L12 Unfortunately, it blocks users from accessing the Core's store with typing relevant to the TextAnnotation 🤷🏻‍♂️
