If you use application config this library breaks in mix release on 1.9

I think it would be worth removing the ability to configure through Application config, as it should be discouraged (that's not what application config is for) and it currently wont work if you use mix releases in 1.9 because of this bug: elixir-lang/elixir#9225

I'd be happy to make a PR, would have to be a major update though, as it will be breaking for people who are using application config.

How would you suggest doing config for a library like this? It doesn't seem like you should need to run a process in your supervision tree to be able to use a library like this.

I would suggest no config and have the config be runtime arguments or options to the given function.
