Description
Julia is generally a much faster language than R, especially when doing lots of computations. Given that JuliaCall lets you use Julia very easily from within R, I'm wondering if it would be a good idea to recode the more computationally intensive parts of PSIS in Julia. I can fire up a pull request if @avehtari or someone else points me at the parts of the package that would benefit most from being rewritten in Julia.

Research direction
The issue names no files or tests. Start by locating the computationally intensive parts of PSIS in the R package and assessing whether JuliaCall is appropriate; done requires maintainer agreement on a target and evidence that a Julia rewrite improves performance.
