allow specification of arm power directly with Laser.ArmPower
Allows specification of the arm power directly with the variable Laser.ArmPower instead of using the input power Laser.Power. This functionality is on superQK. Only one or the other can be specified.
For example, to change the A+ arm power to 800 kW
del ifo.Laser.Power
ifo.Laser.ArmPower = 800e3
The same can be accomplished by inheriting a yaml file like
+inherit: "Aplus"
Laser:
Power: <unset>
ArmPower: 800e3
