[Idea] Progres bar for spacy pipeline

[laugustyniak]

I'm generating scatter text plots for quite a big collections of documents [e.g., 1M+ sentence] and it would be nice to have a progress bar of how many documents have been already processed. I started to dig in where to add. i.e., https://pypi.org/project/tqdm/. @JasonKessler can you help where would be the best place to add it?
