Add cranking IAC taper duration multiplier

[Krakert]

I was wondering, would it be useful to have an After cranking IAC taper duration multiplier override table?

I enabled the Override cranking IAC CLT multiplier to change the IAC position based on the temperature, which really helps when the engine gets warm and doesn't get too much air when cranking.

But the After cranking IAC taper duration is always a fixed (in my case, 200 cycles) number. When an engine is warm, the IAC could taper down sooner because we don't need to hold the RPMs as high and for that long.
