TypeScript support

[alem0lars]

The following are the types to include typescript support in your project:

export type UnhookFunctionType = () => void;
export type HookOpts = { silent: boolean; once: boolean };
export type HookCallback = (str: string, enc: string) => string | boolean;

export function stdout(
  opts: HookOpts | HookCallback,
  cb?: HookCallback
): UnhookFunctionType;

export function stderr(
  opts: HookOpts | HookCallback,
  cb?: HookCallback
): UnhookFunctionType;

They should be added to index.d.ts in order to provide types out-of-the-box.

Sorry, it's better to publish them to DefinitelyTyped sindresorhus/ama#439. We don't care in maintaining typedef ourselves.

I now accept TypeScript definitions if anyone looking is interested in submitting it here.
