Typescript support

Add type annotations so the module can be used in ts projects

[HarTstaRx]

I've submited a PR to DefinitelyTyped, in the meantime this worked for my project:

• Create a index.d.ts file under a new "types" folder in the root of the project.
• Make sure your tsconfig.json has baseUrl and paths correctly filled.

@HarTstaRx why not just PR your typing here so we can have a ts version. Just clone this project, use npm i $path_clone_dir from within your project, then run npm run build:lib:watch to watch for change, add the typing, if you got any issue just ping me here and I'll have a look.

@kopax because the issue was unattended for 3+ months and commits were made 3 days after the issue was open.
The package for the types is already published on npm, you can check the typings here.

@HarTstaRx ok I understand now. This could be added into README. I personally do not use type so I don't know how to test and validate it. I'll leave the issue open until someone resolve it somehow.

[HarTstaRx]

@kopax no worries, the issue can be closed, the typings are publicly available now and everybody should be able to work with this library on typescript from now on. Thanks for your work on the library, saved me a lot of work :)
