Allow floor speed changes based on sensor values

Given a group of sensor values, the average of those sensor values will
be used in selecting the floor speed for the zone. Each time the speed
is set/updated, any speed requested lower than the current floor will be
overwritten with the floor speed to not allow speeds below the floor.
