Returns PropertyDecorator
A PropertyDecorator that sets up automatic subscription to the current user
Remarks

Updates: The decorated property with the User object

Lifecycle: Automatically subscribes in connectedCallback and unsubscribes in disconnectedCallback of the component.

```
@State()

@SelectCurrentUser({
    map: [(user) => user?.fullname]
})

@SelectCurrentUser({
    map: [
        (user) => user?.fullname,
        (name) => name?.split(' ').map(n => n[0]).join('').toUpperCase()
    ],
    filter: [(initials) => initials !== undefined]
})
private userInitials: string;
