Problems with latest master of AWSS3

Hello,

I based on suggestion in https://github.com/JuliaWeb/Requests.jl/issues/171 I have moved to latest master in AWSS3.jl. Nevertheless, I experience errors and the whole library seems to be broken, as I have described in https://github.com/samoconnor/AWSS3.jl/issues/14. Does anyone have similar issues?

Thanks for answers,
Tomas
