Title: Delayed nonblocking send

Additionally this adds support for delayed nonblocking send/streaming.

You can create an ltn12 source which returns just an empty string if there is not data avaible yet.
When data is available, the source just returns data, if the data is streamed till the end nil is returned as before.
