Feature/#117 tokenize tei

Feature

Summary

This MR provides an in-memory tokenization of all relevant text nodes. Each word is wrapped in a tei:seg with a unique ID which reflects its node identity.

This tokenization is applied both before the HTML and the annotation creation so that words in the text panel can reference entities of the AnnotationAPI and vice versa.
