Latin Hypercube sampling as a state space sampler

[Datseris]

Latin Hypercube sampling is a technique to randomly, yet more uniformly, sample a hypercube. https://github.com/MrUrq/LatinHypercubeSampling.jl

Thankfully, there is a Julia implementation of a much more advanced version of the algorithm: https://github.com/MrUrq/LatinHypercubeSampling.jl

We should use this in the state space sampler functionality

(and while we are at it, we should also make the state space sampler work via the type system and multiple dispatch, not with random keywords all given to the same function...)
