Implements the ISAAC and ISAAC-64 random number generators.
ISAAC stands for "Indirection, Shift, Accumulate, Add, and Count" which are
the principal bitwise operations employed. It is the most advanced of a
series of array based random number generator designed by Robert Jenkins
in 1996[^1][^2].
ISAAC is notably fast and produces excellent quality random numbers for
non-cryptographic applications.

## Crate Features
`rand_isaac` is `no_std` compatible. It does not require any functionality
outside of the `core` lib, thus there are no features to configure.
The `serde1` feature includes implementations of `Serialize` and `Deserialize`
for the included RNGs.
