Loads the special call wrapping settings for functions in the specified
    package. This allows the result of the original method call to be cast as a
    different type, or passed to a different constructor before returning from
    the wrapped function.

    Args:
        packname (str): name of the package to get config settings for.
        package: actual package object.
