Function build_extend_arrays 

fn build_extend_arrays<T: ArrowNativeType + Add<Output = T> + CheckedAdd>(
    buffer: &Buffer,
    length: usize,
    start: usize,
    len: usize,
    dest_last_run_end: T,
) -> Result<(Vec<u8>, Option<(usize, usize)>), ArrowError>

Build run ends bytes and values range directly for batch processing
