You have to specialize the code for non-primitive types. There is no other
option. I would say specialization of methods like `compare, update` inside
`InternalStatisticsImpl` is the right and simple way to go forward. This class
should be responsible for handling the statistics updates.
ColumnWriters will just have an instance of the InternalStatisticsImpl and
call the corresponding methods to `update` on writing a new value.
