What is the replacement for [`HTTP.Handlers.StreamHandlerFunction`](https://juliaweb.github.io/HTTP.jl/v0.9/public_interface/#HTTP.Handlers.StreamHandlerFunction) in post 1.0 HTTP.jl package?  
I have a server that handles requests, but with a single endpoint with streaming HTTP connection, in 0.9 I could just write the following to switch from `HTTP.Response` to `HTTP.Stream`:

```julia
function my_run(io::HTTP.Stream)
    startwrite(io)
    write(io, "hello")
    ...
    closewrite(io)
end
HTTP.@register(ROUTER, "GET", "/run", HTTP.StreamHandlerFunction(my_run))

```

In latest version I see just `streamhandler` that does the opposite: transforms `HTTP.Response` to `HTTP.Stream`.

UPD: Found an ugly solution - serve with `stream` flag set, make a router handler the first one in middleware sequence, and past the full sequence at every request endpoint, starting with streamhandler, like here:

```julia
HTTP.@register(ROUTER, "GET", "/another_function", another_function |> JSONMiddleware |> CorsMiddleware |> HTTP.streamhandler)

```
