Include all Data Models & Types (js)

[medallyon]

I use this somewhat extensively throughout my project and I thought it would be neat to flesh out this library with all of the data models & types found at the discord docs. I don't know typescript so if this looks useful, someone would have to make an effort to translate that code and remove any redundancies. Thanks.

Well this library only provides enums related to interactions, and functions for validating request signature headers (if you're using interactions over outgoing web-hooks). So this repo won't be a good place to add all the data models and types. If you or anyone are looking for typings, maybe this repo may help.

Thanks for the PR! But I do think this is the kind of thing we want to leave to discord-api-types.
