Taxonomy validation (Phase 1)

Description

In regards to the validation utils, I completely agree that it eventually needs splitting. In fact, most functions there correspond to the labelling approaches (and using it to label our taxonomy with entities or journals). I'll rename it to "labelling.py", and create other py files as per your request for subsequent work, if necessary.

@emily-bicks I pushed some additional code (relating to the histograms, mostly). I was thinking of directly merging to dev since you already reviewed its legacy code, but maybe you want to have a quick peak again. Otherwise I can merge :)
