Are you sure this is correct? These headers are from the HTTP response, and I'd expect requests to return the same type consistently.

This seems to be the cause of a false positive on this line found by mypy-primer: https://github.com/yurijmikhalevich/rclip/blob/98a2454b988986f6ed67ae6e9fe3342ea82e0f92/rclip/utils.py#L92
