EN_saveinpfile creates invalid controls for GPV valves

[lbutler]

If you have a model which uses open/close controls on a GPV valve, using en_saveinpfile will create controls that references the index of the head loss curve instead of the status.

Original Controls

[CONTROLS]
LINK THE_VALVE  Open    If Node VALVE_DOWN  Below   0
LINK THE_VALVE  Closed  If Node VALVE_DOWN  Above   10

EN_saveinpfile Controls

[CONTROLS]
 LINK THE_VALVE 2.0000 IF NODE VALVE_DOWN BELOW 0.0000
 LINK THE_VALVE 2.0000 IF NODE VALVE_DOWN ABOVE 10.0000

The replit below runs a working network with a controlled GPV, saves it as a new INP and attempt to open it, which fails. You can see the original INP network.inp and the generated one network-by-toolkit.inp on the side panel
