New-rule: force re-export style

Here is a proposal for a new rule: forbidding imports followed by equivalent exports, and prefer re-export syntax instead.

Example:

```typescript
// Forbidden
import { obj } from 'module'
export { obj }

// Allowed
export { obj } from 'module'
```

I didn't find any similar rule in the docs, and I think it would be nice to have one to enforce consistent styling of re-exports.
