Add some sanity checks to prevent conflicts between certain settings - if user selects Smoker Type = "Separate Heat & Fan" then two options related to the Aux Output must be disabled, because the Aux Output will be reserved for the smoker fan. These two are "Auto Flash the Aux Output with Canon" and "Flicker Lights during Engine Start." If we are not using the Aux output for the smoker fan (Smoker Type = "Combined Heat & Fan") then we permit those settings, but only one can be active. If both are active, we disable "Flicker Lights during Engine Start" and keep "Auto Flash the Aux Output with Canon." In reality, all these conflicts are already prevented from occuring by OP Config, but it is good practice to have the board firmware catch them as well.
