Function partition_bound_annotations 

pub fn partition_bound_annotations<A>(
    expr: BoundExpression,
    annotations: BoundAnnotations<A>,
) -> VortexResult<BoundPartitionedExpr<A>>
where
    A: Display + Clone + Eq + Hash,
    FieldName: From<A>,

Partition an already-annotated bound expression tree.

Prefer partition_bound when annotations can be derived by an AnnotationFn.
