GraphQL implementation in Haskell

Simple Haskell CI/CD

This implementation is relatively low-level by design, it doesn't provide any mappings between the GraphQL types and Haskell's type system and avoids compile-time magic. It focuses on flexibility instead, so other solutions can be built on top of it.
