Merge pull request #54 from verpeteren/verpeteren/port-to-simdeez2

I finished the port to simdeez2 with the help of @valadaptive and @arduano 🎉 
This PR needs more engines in the simdeez library exposed. Hence [this PR](arduano/simdeez#74).

Because there were some bugfixes along the way, the output of the various noise generators might slightly differ.
There are probably things that are slightly broken and the _f64 variants were done on a best effort basis.

Let's merge this in and improve from there!
