Multi
A custom type of Listener that allows methods annotated with MultiHandler or UniversalHandler to be registered for multiple event priorities at once. To use, simply implement this interface and use the custom register method to register the listener with the plugin manager. Methods annotated with MultiHandler will be registered for the specified priorities, while methods annotated with UniversalHandler will be registered for all priorities.
All methods should be formatted as fun methodName(event: Event, priority: EventPriority)
