unused_private_fields removes fields referenced from other fields

https://github.com/getgrit/stdlib/blob/main/.grit/patterns/java/unused_private_fields.md

Code:

public class Test {

    private static final String HELLO = "Hello, ";
    private static final String WORLD = "World";

    private static final String HELLO_WORLD = HELLO + WORLD;

    public static void main(String[] args) {
        System.out.println(HELLO_WORLD);
    }
}

Command: grit apply unused_private_fields

Output:

public class Test {

    private static final String HELLO_WORLD = HELLO + WORLD;

    public static void main(String[] args) {
        System.out.println(HELLO_WORLD);
    }
}

Same applies to non-static fields
