React-native-paper: Add TypeScript Definitions

[timwangdev]

Current behaviour

Has built-in flow definitions.
No definitions for TypeScript.
No definitions on https://github.com/DefinitelyTyped/DefinitelyTyped .

Expected behaviour

If it's likely for official to maintain a index.d.ts definition file in this project? This is recommend to keep the definition sync with code and maybe add test for this.

Or I could create the community-maintained definition at DefinitelyTyped.

I think we're not opposed to keep the definition file here, especially if someone is willing to make it work :)

For now, I don't have time to do it by myself, but I can help on it if needed. Let me know.

I've decided to give react-native-paper a shot, and ported some definitions from flow already.
Not sure if I'll stick to this module, but I can submit partial PR. Or maybe I can create work-in-progress PR and add contrubutors

@doomsower awesome, WIP PR is better than no PR :)

Note for everyone, I already created type definitions for 1.x branch and submitted a PR, so if anyone is working on type definitions for 2.x branch, they can get the 1.x version from me for saving some time 👍 .

Yeah, I know. They are kinda messy, because everything is written in one file, and there are no tests, but they will definitely help.
