Bundle sizing / Axios

This release dramatically reduces the bundle size by replacing request and request-promise with axios

It may break some builds if anyone is using it already (which seems unlikely) as the streams now return a promise.

Clarify initial example

Minor change to make the first example actually run on its own in case that confuses people and they think it doesn't work.

Browser Support + Older Node versions

This release bring browser support and ability to use on probably all Node versions >=4.

As I have had some chance to use the api I am happy to mark it now as v1.
