Add CI and make a first release, version alpha

[bnlawrence]

We need to get this properly released, likely including binary wheels given the C code included. But functionality and performance are good.

@valeriupredoi I think we agreed we can proceed with this, and that you are not worried about managing the binaries within it? So we are good to go for release on this one at least.
