Remove rand_hc (#1156) 
* Remove `rand_hc`

We no longer need it for `rand`, so it can be moved to the `rngs`
repository.

c60b7cd21b Remove special cases for emscripten 
Because emscripten supports 128-bit integers now, we no longer have to
add special cases for it. In particular, we can now use ChaCha12 on all
platforms.

14d55f8664 Group Zeta and Zipf with rate-related distributions 
Arguably, the Zipf distribution is related to the Pareto distribution
[1].

b06c2f61af Don't claim Zeta follows Zipf's law 
It seems like this is not true [1], at least not with the same exponent.
