ERROR: MethodError: Cannot convert an object of type Nothing to an object of type String

Hello,

Reading DataPackage country list seems to raise an issue with this library

julia> using DataPackage

julia> data_url = "https://raw.githubusercontent.com/datasets/country-list/master/datapackage.json"
"https://raw.githubusercontent.com/datasets/country-list/master/datapackage.json"

julia> package = Package(data_url)

@scls19fr bonne année! Thanks for raising. Did you find a workaround? It looks like a condition that should be handled in our code. I'll try to look into it.
