docs: Decodes json into a conjure bean type (a plain bean, not enum
          or union).
  
          Args:
              obj: the json object to decode
              conjure_type: a class object which is the bean type
                  we're decoding into
          Returns:
              A instance of a bean of type conjure_type.
