Hypergraph Interchange Format invitation

[colltoaction]

Hi! I'm Martín and I'm a developer working in the HIF project, an effort to share hypergraphs across many libraries, developed by members of HyperNetX, XGI and other established libraries. We are looking to expand the community actively reaching out to higher-order network analysis, topological deep learning, and applied category theory libraries.

I hope you consider checking our repository where we provide the specification of a standard JSON format. Reading your docs and code, I think it would be straightforward to add to_hif and from_hif methods in the IO package. There are so far 4 implementations, each one with its tutorial. I hope this standard will be a solid foundation for researchers to collaborate.

Let me know what you think and any way I can help make this happen!
