   I am back from holiday, and continue to work on this today.
   
   Because for simplicity for the initial pr, I just:
   - Implement the blocked version `GroupValuesPrimitive` for `GroupValues`
   - and `PrimitiveGroupsAccumulator` for `GroupAccumulator`
   
   And actually still don't have such a simple query can show the improvement 
now...
   
   And for showing the improvement, I add an new query in 
`clickbench/extended.sql`:
   ```sql
   SELECT "WatchID", MIN("ResolutionWidth"), MAX("ResolutionWidth"), 
SUM("IsRefresh") FROM hits GROUP BY "WatchID" ORDER BY "WatchID" DESC LIMIT 10;
   ```
