Issues with the Typescript types of this package

[Svish]

The type returned by extract seems to be thought as a discriminated union, but the way it's written, it doesn't actually work as one.

This means it for example is not possible to access the html property of a response with type: 'video', even after checking that the type is indeed 'video'.

import { extract } from '@extractus/oembed-extractor'

const data = await extract('https://vimeo.com/6428069');

switch(data.type) {
    case 'video':
        console.log(data.html)
        break;
}

Exampe on TS Playground

I also notice there's a lot of optional fields on all the types in this project. Would be good if they could be non-optional, so we don't have to constantly check whether something is there or not.

@Svish thank you for you notice, could you modify the type definitions and make a pr?
