Add support for parsing queries from a String (in addition to a block)

[ateamlunchbox]

Greetings. I've been using this library and it is very helpful.

I'd like to be able to parse a query from a String, not just a block.

Tests included.

Please let me know if this is acceptable.

Thanks.

Excellent work.

This needs to be documented in README, please.

I also made some nitpicky comments on the specs. Would appreciate if these could be addressed, but not required.

Updated. What's the release schedule? Is this something that would be released in the next few days?

Thanks.

@ateamlunchbox thanks for you contribution, do you want to help co-maintain and make the next release following the RELEASING doc? otherwise i can do that later today 🙌

@ashkan18: Thanks for the invite. I'll hold off on becoming co-maintainer for now. If I end up making other contributions in the next couple months then I can sign on as a co-maintainer.

Awesome! I'll cut a new release in few minutes and will let you know 🙌
