> Two approaches - a separate decoding path, into rows instead of VRBs; or decoding VRBs
into rows on a higher level (the original LlapInputFormat). I think the latter might be better
- it's not a hugely important path, and perf in non-vectorized case is not the best anyway,
so it's better to make do with much less new code and architectural disruption. 
> Some ORC patches in progress introduce an easy to reuse (or so I hope, anyway) VRB-to-row
conversion, so we should just use that.
