Add Spacy Tag explorer to elements widget

[ThijsVroegh]

Add option to highlight all or a specific spacy category, if selected. Similar to the current setting widget (where different setting-related aspects can be highlighted in different colors), we want to create complete flexibility to highlight such categories. Output should probably be made available as part of the elements widget
