Function apply 

pub fn apply(
    lhs: &ColumnarValue,
    rhs: &ColumnarValue,
    f: impl Fn(&dyn Datum, &dyn Datum) -> Result<ArrayRef, ArrowError>,
) -> Result<ColumnarValue>

Applies a binary Datum kernel f to lhs and rhs

This maps arrow-rs’ Datum kernels to DataFusion’s ColumnarValue abstraction
