add other org members?

[StefanKarpinski]

There are no public organization members and no code in this repo, so I don't even know who to contact about getting added as a member and about adding @rforquet so that we can start to collect Julia RNGs in one place, so I'm opening an issue here. It would be good to start to build a Julia community around RNGs like PCG (if there's code, it would be nice to publish it) and https://github.com/rfourquet/StableRNGs.jl.
