Add stanza constituency output about spacy-stanza HOT 2 OPEN

Sorry for not getting back to you about this sooner. I think my main concern would be that it sounds like it's going to be relatively hard to use this annotation from a spacy Doc. I haven't looked into how they store the constituency trees in detail, but using plain stanza with its original data structures sounds like it might be better from a usability perspective? What do you think are the advantages of having this in a spacy Doc?

A tree is an iterable of subtrees with ultimately Words as terminals and linguistic categories as intermediate nodes. From that perspective, I was thinking of having a similar Tree structure in the spacy_stanza API that used spaCy Tokens instead. You'd still be able to traverse the constituency tree as per stanza API but the terminals that you get out of it are spaCy tokens. I might be biased, but this would be useful in my own research where I want to use constituency trees on the one hand as well as spaCy's extensibility for my own components.

As always, if this does not seem useful for the wider user-base to you, then we can close this topic.
