AllowedValues

```
@Retention(RUNTIME)
@Target(FIELD)
public @interface AllowedValues
```
Annotation that marks that the option/arguments are restricted to a given set of values
Unlike AllowedRawValues this restriction works against the values after they have been converted into Java objects and thus can provide more accurate restriction than AllowedValues can provide. The trade off is that enforcing this restriction is marginally more complex because it requires parsing the allowed values.
