Title: Fix gh-914, Ensure CSV headers skipped

It was assumed the csv header lines, existed on the 1st node, but they might
exist on any, and/or span nodes.
If a csv input has a header, it will now mean that the nodes must wait until
signalled by the previous node before proceeding. Once the header lines are
consumed, the consumer will signal all remaining nodes immediately.
Superfile with CSV's make this particularly nasty to deal with, as they may
have headers that start or span different nodes to each other.
