De/highlight text entities on data type change
goal the highlighting state has to be adjusted whenever the selection of the annotation types changes.
presumption: persons, places and the option highlight all are selected.
result: all the annotations in the annotation list are highlighted as well as the appropriate text entities.
use case: a user toggles an annotation type, e.g. places
expectation: places are removed from the annotation list and the text entities will get dehighlighted
TODO: de/highlight all text entities in the text panel whenever the annotation types are toggled
