[client-v2] Fix support in ClickHouseBinaryFormatReader for SimpleAggregateValue

[Am-phi]

Summary

This is a response to #2127 which is complementary to #2022. I'm however concerned by my solution as it is, it may be contested or refused. The solution proposed here is by adding a specific check for each operation that gets the dataType to check if it's a simpleAggregateFunction, and if it's the case take the nested column datatype. Maybe a modification of the ClickhouseColumn implementation could be cleaner but its scope is above my understanding at this moment.

Closes #2127
