Listener.stop() method breaks API since declared abstract #1770

In #1724, the can.listener.Listener.stop() method was decorated as an @abstractmethod, without any further explanation. This seems to work alright within the python-can codebase, but other dependent projects will get in trouble if they don't implement that method on derived classes. At the very least should this API change be documented prominently.

This actually causes trouble with e.g. https://github.com/christiansandberg/canopen/, see https://github.com/christiansandberg/canopen/blob/713f005af8a6787a4ff54a26f55fa6736f86abaf/canopen/network.py#L346

Expected behavior

This API change should be clearly documented OR reverted, going back to the empty default implementation.
