Push out a new version

[bjarki]

First of all, thank you for writing this package. I would like to use it in a project, but I can not downgrade :httpoison to version 1.8.

I have pulled down your code, and I'm able to use it as a local dependency since the code in main supports :httpoison 1.8 or 2.2 960f59b

Can you push out a new version to hex.pm

@jakobht I would second that. It would be really great if you could upgrade the httpoison dependency to the latest version and push out a new version.

Thanks for providing this library.
