Function resolve_async 

pub async fn resolve_async<F, Fut>(
    fetch_url: F,
    refs: &[PartitionRef],
) -> Result<Vec<ResolvedPartition>, TesseraError>
where
    F: Fn(PartitionRef) -> Fut,
    Fut: Future<Output = Result<String, TesseraError>>,

Resolve presigned URLs for refs concurrently, preserving order.
