Support lit-element?

[Jack-Works]

render() {
        return html`Web Components are <span>${this.mood}</span>!`;
}

Lit-element need a html`string` but this transformer seems only emit `string`

Could you expand a little more in what is the expected input&output here?

[Jack-Works]

e.g.
Input

<div />

Output

html\`<div />\`

You can see the document of lit-element. It's a framework use tagged template string as it's template

I think this feature escape the scope of the project a bit... but why not, I think it shouldn't be that hard.

I plan to add it under an option, something like output: lit-element or something like that, What do you think?

I'll probably work on it when I have time, you're free to look up the code and make a PR 😄
