This still addresses the demonstration notebook #40, which lacked a way to visualize the results. Visualization can still be improved further, as this method highlights every occurence of an ORG, LOC or MISC, while in reality only one occurence is replaced at a time in the pseudonymization process. This can lead to parts of the text being highlighted, although it was not replaced in the pseudonymization. For PER, the highlighting is working accurately, since the pseudonymization class replaces every occurence of each name as well.

This crashes when parsing too many emails though, something to keep in mind for further testing (did not display anything anymore / the kernel died for two separate tests on vscode / using jupyter-notebook).
