Trait LayoutChildren

    // Required methods
    fn to_arc(&self) -> Arc<dyn LayoutChildren>;
    fn child(

    ) -> Result<Arc<dyn Layout>, VortexError>;
    fn child_row_count(&self, idx: usize) -> u64;
    fn nchildren(&self) -> usize;
}

Abstract way of accessing the children of a layout.

This allows us to abstract over the lazy flatbuffer-based layouts, as well as the in-memory layout trees.

fn child( &self, idx: usize, dtype: &DType, ) -> Result<Arc<dyn Layout>, VortexError>
