wow! I also want to look into this in more detail, it looks promising.
@StephanEwen if you find a bit of time, can you write some more details to
guide the reviewing a bit? Kudos for the high quality work!

> Time panes are commonly used for aligned time windows (tumbling and sliding).
> These utilities would represent the panes with per-pane keyed state.
> The implementation must support:
> - Evicting panes efficiently
> - iterating over the union of all panes' state per key for all keys
> (computing the window function for all keys)
> - efficient append the state for a key in a random pane
