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.

a6623ccbf7 rand_distr: Port benchmarks to Criterion 
- The benchmarks are now living in their own crate. Therefore, this does
  not add any dev-dependencies to rand_distr.
- Instead of bytes per seconds, we now measure cycles per byte.

Refs #1039.

e0e13d79c6 Create a distribution by mapping the output of another one 
This is useful if consumers are to be given an opaque type implementing the
Distribution trait, but the output of the provided implementations needs
additional post processing, e.g. to attach compile time units of measurement.
