You are right that we cannot make [Type]ColumnStatisticsImpl inherit
ColumnStatisticsImpl. That is why I introduced `InternalStatisticsImpl` in
ORC-185.
With that, you will just use `InternalStatisticsImpl<Type>` in your
templated [Type]ColumnWriterImpl.
I guess without the design for the ColumnWriter, it is hard to discuss at
this point.
Can you open a separate PR for your ColumnWrite code? Things will get more
clear then.
We can converge on the necessary overall changes.
