Integer-based Indexing

[ilan-gold]

Is there any plan for an integer-based chunk (or array) indexer i.e., one that doesn't rely entirely on ranges (+ chunk indices if chunks)? It seems like ndarray is already a dep so this shouldn't be too hard (knowing nothing about ndarray at all)? I'm going to prototype something any so if you're interested, could be a contribution, and we can make this an issue.

But if it already exists, please point me to it!

It doesn't exist, but sounds like a handy addition!

Moving to issue!
