+- **Typestate design refactor**: The GrancClient has been refactored to support multiple states where invariants for each state are ensured by the compiler. ([#28](https://github.com/JasterV/granc/pull/28))
+  - The GrancClient can be in either a `WithServerReflection` state or a `WithFileDescriptor` state, and both states have independent APIs (Async vs sync).
