reorder_nodes allows reordering
the nodes in an existing FFT definition
(in the tidy data frame format).
reorder_nodes allows to directly set and change the node
order in an FFT definition by specifying nodes.
When a former non-final node becomes a final node,
the exit type of the former final node
is set to the signal value (i.e., exit_types[2]).
