Ship Type Definitions

[stefnotch]

This library is really well made, thank you for all your hard work!

Since most packages on npm have Typescript definitions, I wanted to ask whether that would be welcome here as well. As I understand it, simply adopting ES modules and adding Typescript and might not be the best option. After all, this library tries to keep its size down to a minimum.

I'd love to add Typescript definitions, in whatever form you think would be best.

With fraction.js we have type definitions already: https://github.com/infusion/Fraction.js/blob/master/fraction.d.ts

You're more than welcome to add a type definition file for complex.js in a similar way!
