List of RDFJS libraries

I minimally updated the "Comparison of RDFJS Libraries" a little while ago
(actually, a month). It's broken down into purpose (i.e. parsing a
serialization, producing a serialization, or querying a graph), and lists
which features/standards that each library supports.

https://www.w3.org/community/rdfjs/wiki/Comparison_of_RDFJS_libraries

Could I get help in adding more implementations? (Or just let me know here.)

If there's any other features that you can think of that would be good to
index by, of course, feel free to add columns.

Thanks,

Austin Wright.
