Feature Request: /rs clearall entity should not remove renamed entities

[OtakuSweett]

Description:
I propose that the /rs clearall entity command should not remove entities that have been renamed with a tag. This would be useful for several reasons:

1. Preservation of Important Entities: Players often rename entities to identify them or assign them a specific purpose. By preventing these entities from being removed, important elements of the game are preserved.

2. Improved Game Management: Allowing renamed entities to remain ensures better resource and entity management within the game. Players can trust that their tagged entities will stay intact, even when using cleanup commands.

3. Customization and Creativity: Players frequently use custom names for their entities as part of their creative builds. Protecting these entities encourages creativity and personalization within the game.

Additional Example:
Furthermore, I suggest that when an entity is renamed, it should not stack with other non-renamed entities. If they are already stacked, they should be able to separate. This would allow for better organization and handling of renamed entities, ensuring each one maintains its unique identity.

You can enable dont-stack-custom-named in the config.yml which will prevent custom named entities from stacking together. That way the /rs clearall command won't clear them, since they will all be individual entities and the command only clears stacks.
