Review comment:
This is the individual progress for each element and restriction pair for a
splittable DoFn. The aggregation is interesting since if you sum across all
**latest** values then that tells you the amount of completed work globally and
the amount of known but not yet finished work globally. Note that this won't
cover the amount of unknown work (e.g. elements and restrictions that have yet
to be processed).
@robertwb / @ajamato What do you think about adding `ELEMENT` as labels
(storing the encoded element and restriction) and then we could use
`LATEST_DOUBLE_TYPE`?
