* Async function that returns a `stream.Readable` instance to the
|
* callback function that will output the contents of the given URI.
|
*
|
* For caching purposes, you can pass in a `stream` instance from a previous
|
* `getUri()` call as a `cache: stream` option, and if the destination has
|
* not changed since the last time the endpoint was retreived then the callback
|
* will be invoked with an Error object with `code` set to "ENOTMODIFIED" and
|
* `null` for the "stream" instance argument. In this case, you can skip
|
* retreiving the file again and continue to use the previous payload.
