Ethereum Dependency Failure - Coincurve

[ghost]

Building out the docker image and running python3 setup.py experimental --blockchain=ethereum to have it build out / install the ethereum setup, I'm running into an issue installing the pyethereum dependency, Coincurve.

More than likely more ethereum dependency hell. Probably need to update rlp & pyethereum versioning to fix this. We first locked down RLP due to a bug, then had to lock down pyethereum. I believe RLP is good now so we should update these dependencies.

Setting Coincurve to 7.1.0 (down from 9.0.0 - I've looked and not too big of changes: https://github.com/ofek/coincurve#history) seems to work. I've created a PR for it and made an issue on Coincurve to hopefully get more insight into this issue.
