Format derive attributes alphabetically

[Feature Request] 

Please add a feature to automatically format `#[derive(...)]` attributes in alphabetical order by default.

```rs
// Current (not sorted):
#[derive(Ord, PartialEq, Eq, Hash, Debug, Clone)]

// Desired (sorted):
#[derive(Clone, Debug, Eq, Hash, Ord, PartialEq)]
```

Thank you!
