In Lyra-based project all UObject`s are primary

[Son1XI]

In Lyra-based project all UObject`s are marked as primary asset type, so all assets considered as used, because plugin logic works for ignoring all primary classes (and derived ones).
Workaround for me: inside GetClassNamesPrimary method if class path is /Script/CoreUObject.Object - skip adding to ClassNamesPrimaryBase. But I wish a better one solution, thanks!)

@Son1XI But thats kinda contradicting the main logic, if asset is primary and derived assets is primary, ignoring them will make possibility to remove assets that are used in project. Not sure ignore UObject classes are good idea, maybe some example would be nice so i better understand whats not working in your case.

Another thing that i mentioned in this issue #47 , is yea maybe its good idea to expose settings for what user considers used for manual tweaking.

Try to run the Lyra project (sample from Epic) - https://dev.epicgames.com/documentation/en-us/unreal-engine/lyra-sample-game-in-unreal-engine. Create any asset there that is definitely not used (a blueprint of any class that you do not place anywhere). And run your plugin, you will notice that it will not output anything. If you start debugging, it will turn out that it considers all files inherited from /Script/CoreUObject.Object (that is, literally all files) - are files that are used. This is a feature of Lyra, because of which the plugin does not work

Well, @Son1XI , you are correct, this is bug definitely. I will dig into it.
