jcenter issues

Latest version of this library uses Ktor 1.3.2 which it's getting from jcenter (with all the associated issues that's causing these days). I realise this isn't being maintained but just in case anyone is planning on updating dependencies?

Go for it, PRs are welcome!

I think #59 should go a long way towards this.
