chunked encoding support

[ilovenwd]

some api returns data stream in chunked encoding.
Excon support this, but heroics didn't support it.
It would be nice if the result of heroics api call could be each-ed

Seems reasonable. What's the behavior that currently happens when you send heroics a chunked response? Does it fail or error or gracefully degrade? Can you provide an example app or repro to demonstrate this behavior so I can verify this feature has not yet been implemented (https://www.codetriage.com/example_app)? Also, it will help anyone who wants to work on such a feature in the future.

Excon support this

Can you send an example of a project that uses excon and supports chunked encoding?
