Clean up API/API documentation

Hey, I was looking at the overwatch-api npm package’s documentation and I saw that the callback supposedly takes two arguments, err and data, where err contains error info and data is the response from the server, but as far as I can tell the second argument data is never actually used, and the first argument is used for both. I’m currently in the process of making a TypeScript types declaration file for the overwatch-api package so it would be helpful if you could either fix this or point me in the right direction for how the package works, thanks!

P.S. I really appreciate the work you’ve done on this package, nice to not have to manually figure this out myself 👍

Here are the completed TypeScript types, it isn’t available by doing npm install @types/overwatch-api or yarn add @types/overwatch-api just yet but the bot that they have to automatically add types should do that soon 😃 Let me know if you have any feedback, this is my first type declaration file of any meaningful size.

Great, thanks! Would love to see the TypeScript types when those are ready. 😃
