Suggestions based on the fse package

Hi,

I'm excited to see how this package grows - if I may, I'd suggest a glimpse at the FSE package roadmap in https://github.com/oborchers/Fast_Sentence_Embeddings/issues/49 for some additions to the TODO things on the README. If a solid Rust base is present for multiple extensions of SIF, it'll make a great base to be used via Python.

I can't wait for a Python binding based on a Rust implementation of SIF and its variants!

Cheers!
