docs: A Callable is a representation of a function in the binary that can be interacted with like a native python
          function.
  
          :param addr:            The address of the function to use
          :param concrete_only:   Throw an exception if the execution splits into multiple states
          :param perform_merge:   Merge all result states into one at the end (only relevant if concrete_only=False)
          :param base_state:      The state from which to do these runs
          :param toc:             The address of the table of contents for ppc64
          :param cc:              The SimCC to use for a calling convention
          :returns:               A Callable object that can be used as a interface for executing guest code like a
                                  python function.
