Allow multiple inputs to thermal and stepwise controllers
Use std::max to determine which input value to apply.
Also start throwing when inputs are empty as otherwise
there will be a nullptr dereference.
Tested-by: Added multiple inputs and application no longer
segfaults and verifed max was being used. Also added unit
tests.
