[NEW OSL] Async

[Mistium]

do (
  network "getsync" "https://hi.com/text.txt"
) then (
  page_data = data
  data = ""
  page = "loaded"
)

Allows osl to run a command without it stopping the execution of the window. This is likely to be made by creating a clone that runs the code, sends the result back to the original window, then
deletes itself
