Yet another serializer interface

This aims to create an interface that is very much like .NET's Utf8JsonReader/Utf8JsonWriter, while fixing some of the issues faced when with using it in a game engine.

• Efficient Utf8JsonReader like interface.
• Fully AOT compliant, no reflection.
• Interface allows switching between formats.
• Implement serializer for external types with duck typing, or implement IPrimitive<T> for first class support.
• Source generator to automatically implement IPrimitive<T> for your types.
  • Decorate a setter only property with [Obsolete] to provide backwards compatibility.

Binson is a JSON inspired format that has a 1 to 1 mapping of json constructs in binary form, with no additional complexities such as backreferences.
