Increase /Decrease keys for radiator - Request for 4.11.1 or 4.12

[Syrius]

4.11 has introduced a much welcome (IMO) improvement to engine management, with better modelling of engine overheat that requires more detailed adjustments of rpm, radiator, throttle and mixture. As currently implemented, radiator opening is controlled by a single key binding ("Cowl or Armor Flaps" in the controls screen) that keeps increasing radiator setting by 2 notches up to 'Open' and then cycles over to 'Closed' and so on. Because we now need to adjust radiator more often and more precisely, it would be helpful to have two incremental keys available for radiator status: 'increase' and 'decrease', similar to what is available for prop pitch, mixture and throttle. 'Increase radiator opening', for instance, would add a notch to the current setting and would stop at the open setting without cycling over; 'decrease' would work the other way round and stop at closed setting. This would help operating the radiator more quickly and predictably, without risking that one extra keypress will close the radiator when we want to set it open.

I'm aware that radiator can be assigned to a joystick axis, but I simply don't have any additional axes available after assigning the ones on my HOTAS throttle to trim controls and prop pitch, and I'm guessing this will also happen to most users. Would it be possible to add those incremental key bindings for radiator in 4.11.1 or 4.12?

Thanks Team Daidalos for all your work.
