This plugin is inspired by the GameplayMessageRouter in the Lyra project, with some enhanced functionality.
In the original GameplayMessageRouter, you cannot synchronously unregister a listener while receiving a message
because it would result in removing elements during array iteration.
This plugin solves this issue by implementing a MarkDead approach.
To avoid writing custom K2_Node code, this plugin uses Instancedstruct as the type for the payload, and implemented
dynamic types through InstancedStruct while maintaining polymorphism.
