Add support for re-exporting crates ✨

I have a crate that reexports bevy :)

```Rust
use eva_voxel::ecs::system::Resource;

#[derive(Resource)]
struct MyResource {}

fn main() {

}
```

this code does not compile, since the Resource proc macro thinks that it should use `bevy_ecs::Resource` :(

Could we somehow add support so it can work? 😺
