> "Argsort" is NumPy specific name. Other languages/libraries use
> different name:
> * R: order
> *
> https://cran.r-project.org/doc/manuals/r-release/fullrefman.pdf#Rfn.order
> * MATLAB: sort
> * https://mathworks.com/help/matlab/ref/sort.html
> * "sort" returns sorted array and indices to sort array
> * Julia: sortperm
> *
> https://pkg.julialang.org/docs/julia/THl1k/1.1.1/base/sort.html#Base.sortperm
> It's better that we use general name because Arrow C++ isn't a NumPy
> compatible library.
> "SortToIndices" means "sort that returns indices array".
