    Quickstep 28 29

    More efficient handling of aggregations by having a combined payload in the hash table.
This also removes ValueT parametrization for the hash table data structure. Please refer to
JIRA tickets QUICKSTEP-28 and QUICKSTEP-29 for more details.
    TPC-H query 01 sees significant performance improvements with these changes.
    
    Currently, only SeparateChaining hash table type is supported.
