stream with async is broken with curl v3.3

[sckott]

e.g.,

fun <- function(x) cat(rawToChar(x))
fun <- function(x) cat(rawToChar(x))
req1 <- HttpRequest$new(url = "https://httpbin.org/get"
    )$get(query = list(foo = "bar"), stream = fun)
req2 <- HttpRequest$new(url = "https://httpbin.org/get"
    )$get(query = list(hello = "world"), stream = fun)
out <- AsyncVaried$new(req1, req2)
out$request()
#> Error in (function (x)  : unused argument (0)
#> Error in (function (x)  : unused argument (1)

looks like he's changed the expected function structure expected passed to data param
