A Node Red node for resending flow messages.

When a new input message arrives, it will be (re)sent to the output port at specified time intervals. This process will repeat until the next input message arrives, or until the maximum number of resends has been reached.

Thanks to Bart Butenaers for the basement I developed this node out of.
