Add JSONLD support?

[peacememories]

Hi, and thanks for creating this library :)

I'm currently trying to create a JSONLD based REST API for a service, and would love to have JSONLD support in rome for this. I'm obviously willing to do some work to make this happen. Is this something better done as a separate crate or do you think JSONLD support should be integrated in rome?

There are libraries for parsing JSON. JSON-LD is another matter. Translating JSONLD into triples is not trivial. Having support for JSONLD in Rome would be wonderful. To make reuse in other contexts easier, I suggest you put code for going from JSONLD to triples (and back) in separate crate.

However doing it inside of Rome is fine with me too if you think that's better. I will certainly look seriously at pull requests that add this.
