0d6094a3ea sumMap: return types less prone to oveflows
It used to be that sumMap would return the same type as the values
columns. If columns of Array(UInt8) were to be given, that would really
easily cause oveflow. It now uses `getWidenDataType` (and ultimately
`NearestFieldType`) in order to define the result type.
