Integrate TypeScript typings

[DdZ-Fred]

Hello!

I just added the package in a TS project but the typings are missing. Would you be interested in a PR or should I go on DefinitelyTyped to do one ?

I think either would be an awesome addition! 👍 Let's maybe bundle the typings for now and have a PR?

Cool! ok, let's do that then!
