add support for ancient nodes; resolves #3

Add backwards compatibility with older versions of node by using [isaacs/readable-stream](https://github.com/isaacs/readable-stream)

"If you want to guarantee a stable streams base, regardless of what version of Node you, or the users of your libraries are using, use readable-stream only and avoid the "stream" module in Node-core."
