@hynek father I'm about to sin.

I'm going to make cattrs support this:

```
from cattrs import override

@define
class A:
a: Annotated[int, override(rename="my-field")]
```

Someone asked for it and it was easy to do. I kind of like it. It goes against the spirit of correct domain modeling, but... Practicality beats purity and all that.

Any thoughts?
