Progress updates for download

[machisuji]

Hi, I'm using sttp with ZIO to download quite large files via an API.
It looks something like this:

def downloadRequest(uri: Uri, fileName: String, apiKey: String) = basicRequest
    .auth.basic("apikey", apiToken)
    .get(uri)
    .response(asFile(new File(fileName)))

def download(): IO[Exception, File] =
  for
    backend <- HttpClientZioBackend()
    response <- downloadRequest(...).send(backend)
    file <- ZIO.fromEither(response.body).mapError(e => new Exception(s"Download failed: $e")))
  yield
    file

How would you go about getting updates about how far the download is?

This type of use-case would require obtaining the response as a ZIO-Stream, and notifying interested parties asynchronously on the progress. I don't think there's anything to implement on the sttp-client side, hence closing.
