Show annotations within the text, similarly to the INCEpTION interface

[ehrhart]

It's been suggested to display annotations (smell source, carrier, quality, emotion, ...) into the text excerpt in a similar way as with INCePTION.

However in the KG we don't have offsets for each annotation, which means we would have to rely on regular expressions (which might be an issue in some cases?

Some experiments with the UI need to be conducted.
