Spacy is a dependency, despite seemingly not being used or supported

[ghost]

Hi,

I noticed in this comment here that Spacy support has been removed (though I could be interpreting that wrong).

Does this mean it can be removed as a dependency? If so, that would be much appreciated, as it seems to carry a lot of transient dependencies, and also being a Cython extension library only providing manylinux2014 wheels, can be difficult to install on certain platforms.

For reference, this is the dependency tree of anchor-exp 0.0.1.2. As you can see, removing spacy (if possible) would clean this up a lot.

Sorry if I've misunderstood and spacy is infact still a dependency.
