Description
I have a use case where I may need to scan a table for millions of items. I am unable to allocate an array that large. What I really want is to be able to operate on it like a stream. Would you accept a PR adding an overload that returns an AsyncSeq instead of an array? It would require taking a dependency on https://github.com/fsprojects/FSharp.Control.AsyncSeq.
Thank you for all your hard work!

Research direction
Start by locating the existing ScanAsync implementation and the project’s dependency configuration. Review the FSharp.Control.AsyncSeq API and determine how an overload can expose the scan as a stream without allocating the full result. Done means the requested overload exists and its behavior is covered by the project’s tests.
