MetaStackDefinition (LuckPerms API (v5.3))

```
public interface MetaStackDefinition
```
Represents a meta stack model, consisting of a chain of elements, separated by spacers.
The resultant string is constructed as: [start spacer] [element] [middle spacer] [element] [middle spacer] [element] [end spacer]

Definitions can be passed to a users UserData instance using MetaContexts, and the result of this stack can be retrieved from the returned MetaData instance.
