Based on the feedback from the QMC.jl devs we need to restrict lattice rules to shifting and allows scrambling only for digital nets (sobol, faure (to be added)).

Then we should contribute the rhalton sampling to the QMC package to allow for scrambled halton sequences. https://arxiv.org/pdf/1706.02808.pdf
