WIP, just putting this up so I don't lose it. Anyone would be welcome to take this over and finish it.

I'm thinking about adding partialSums and partialProds as a follow-up to #1486. It's not top on my todo list, so this is just a heads up. (However, t's unlikely that I will have time to take up getElem_flatten this calendar year.)

I've made #1515 to add general partial sums and products. I will update this PR to build upon it when I have a chance. There's a chance I can pick-up getElem_flatten sooner than I thought, but if anyone else wants to do it then go ahead!

For getElem_flatten, the translation is basically the same as decodeSigma from #1332
