Review Comment:
`ConsumerRebalanceListenerCallbackNeededEvent` handles 'assign', 'revoke',
and 'lose' callbacks. It was my understanding—I could be wrong—that we wanted
to _wait_ to throw the exception after the reconciliation was fully processed.
That is, not necessarily on the first callback 🤔

Review Comment:
However, this implementation has the interesting property that it will both
throw the exception _and_ continue processing. It seems like this could
potentially yield **two** exceptions, if, say, both the `onPartitionsRevoked()`
_and_ `onPartitionsAssigned()` threw exceptions. Is that the intent?
