The macro input should have a `layout_fn`, and can have arguments passed from annotated function into `layout_fn`. The macro will call the `layout_fn` if the `HX-Boosted` header is not present, otherwise it will return the response directly.
```rust
#[hx_boosted_by(layout_fn, [arg1, agr2, ...])]
```
`#[hx_boosted_by(layout_fn [, arg1, agr2, ...])]`
If `layout_fn` is an async function, use `hx_boosted_by_async` instead.
