Enum SeenValues 

pub enum SeenValues {
    All {
        num_values: usize,
    },
    Some {
        values: BooleanBufferBuilder,
    },
}

If the input has nulls, then the accumulator must potentially handle each input null value specially (e.g. for SUM to mark the corresponding sum as null)

If there are filters present, NullState tracks if it has seen any value for that group (as some values may be filtered out). Without a filter, the accumulator is only passed groups that had at least one value to accumulate so they do not need to track if they have seen values for a particular group.
