Provide the read() side as a stream

[aliafshar]

Cool library! It seems to me to be more useful to provide the read side as a stream. When using with terminal library the readToTerminal is somewhat problematic, and multiple terminals are not swell multiplexed for some reason. I even ran the Lite terminal on linux and multiple terminals don't work correctly. The second blocks while the first one works. I suspect it is from using the executor, but I am not sure.
