Kaloyan Raev f96cc9c955 HTTP Ranger (#11)
* HTTPRanger

* Migrate eestream library to use ReadCloser instead of Reader

* Use MultiReadCloser instead of MultiReader

* Adapt example cli cmds to latest serverbox changes

* Close LazyReadCloser only if only generated

* Close ReadClosers sequentially

* Close response body on unexpected status code

* Avoid double close of the pipe reader

* Better formatting for imports

* Exit instead of panicking
