1.0.0 Release

All planned features and testing are done, so let's call it complete. 💯

I built it into an Electron app with a Node native module and I got GraphiQL working against that, which uncovered some gaps in the Introspection support. I plan on publishing the native module and the GraphiQL app which consumes it as samples under my own account rather than trying to integrate them as complete projects into this one. Relevant code snippets might make their way into the documentation.

I also added runtime @directive support. You can declare custom directives in the schema and they will be included in the Introspection. If you include directives in your queries at runtime, they will be passed to each of the getField interface accessors in a response::Value 2-level map.

To support passing directives and adding future parameters, I defined a parameter block struct service::FieldParams. The signature of the generated interfaces should not need to change again just to support passing new contextual or environmental parameters into them, which will make it easier to perform non-breaking minor-version updates in the future.
