Bryan Boreham e04d137649 [PERF] TSDB: Query head and ooo-head together 
Add `HeadAndOOOQuerier` which iterates just once over series, then
where necessary merges chunks from in-order and out-of-order lists.

Add a ChunkQuerier for in-order and ooo together

Add copy-last-chunk behaviour to HeadAndOOOChunkReader

Out-of-order chunk IDs are distinguished from in-order by setting bit 23.
