Define a request body with `multipart/form-data` media type.

This macro will generate 5 implementations, [`FromRequest`], [`ApiRequest`], [`MediaType`], [`RequestMediaType`] and [`SingleMediaType`].

## Example

```rust
use predawn::{
    extract::multipart::{JsonField, Multipart, Upload},
    ToSchema,
};
use serde::Deserialize;

#[derive(ToSchema, Multipart)]
pub struct SomeMultipart {
    person: JsonField<Person>,
    message: String,
    files: Vec<Upload>,
}

#[derive(ToSchema, Deserialize)]
pub struct Person {
    name: String,
    age: u8,
}
```

## Note

`struct`s can only be annotated with `Multipart` derive macro if all of their fields implement the [`ParseField`] trait.
