Require Julia 1.0

[dnk8n]

I didn't know the syntax to enable the ability for the package to install on both 0.6* and 1.0*

Just thought I would show that this does correctly install on 1.0 and only the REQUIREMENTS file needs changing.

Here is a screenshot of the current stable version of the package on Julia 1.0 failing, and then the version with my amendment passing

Merging this would solve #16 but might break current 0.6 installation. Not sure what needs to be done to support both. I have never worked with Julia in a substantial way before.

Coverage remained the same at 100.0% when pulling dcc1c2d on cape-diff:master into 92586fe on rawrgrr:master.

Would need the automation servers to be on Julia 1.0 to test whether this all works. Is that all configurable via the code in this repo?

So to-do list for this PR:

• Specify REQUIREMENTS so that it works 0.64 - 1.0 (this undertaking might be far too much work. So better to choose one for now IMO.
• If you choose to stay with 0.64, then I can look into incorporating the same automation as you into my fork rather (except Julia 1.0) and have it working on 1.0 there.

Comments on how you want to proceed. And if you could aid me to get my CI working like yours, that would be great.
