Template Enum support

[RylanYancey]

I'd like to use Askama as follows:

#[derive(Template)]
#[derive(Serialize, Deserialize)]
pub enum QuestionData {
	#[template(path = "./templates/question/editor/multiple-text.html")]
	MultipleChoiceText {
		numbering: Numbering,
		text: Vec<String>,
	},

	#[template(path = "./templates/question/editor/multiple-image.html")]
	MultipleChoiceImage {
		numbering: Numbering,
		images: Vec<i32>,
	},

	#[template(path = "./templates/question/editor/truefalse.html")]
	TrueOrFalse,

	#[template(path = "./templates/question/editor/fillblank.html")]
	FillInTheBlank {
		sections: Vec<String>,
		starts_with_blank: bool,
	},

	#[template(path = "./templates/question/editor/short-answer.html")]
	ShortAnswer {
		answers: Vec<String>,
	},

	#[template(path = "./templates/question/editor/ranking-text.html")]
	RankingText {
		numbering: Numbering,
		items: Vec<String>,
	},

	#[template(path = "./templates/question/editor/ranking-image.html")]
	RankingImages {
		numbering: Numbering,
		items: Vec<i32>,
	},
}

#[derive(Serialize, Deserialize)]
pub enum Numbering {
	Letters,
	Numbers,
	Bullets,
}

Is this a possibility in the future?

I'm not convinced. Why do you need this? Alternatively, could you do MultipleChoiceText(MultipleChoiceText) with struct MultipleChoiceText { numbering: Numbering, text: Vec<String> } instead? That should get you pretty close.
