Description
A `hessian` / `hessian!` function in Enzyme would be cool!
Right now the method described in https://enzymead.github.io/Enzyme.jl/stable/generated/autodiff/#Forward-over-reverse uses `BatchDuplicated`. Am I correct in assuming that, like ForwardDiff's "chunks", Enzyme's "batches" are limited in size by memory bandwitch, typically to the order of 10 elements? If so, should there be a Hessian mode that computes HVPs in batches smaller than the size n?
