We now measure two running averages - ambient_slow and ambient_fast.

The _slow is computed based on _fast and few bits of averaging.

We don't want to change the zone too often, but on the other hand,
we want fast reaction to the strong ambient light level changes.
So we compute the new ambient zone based on _fast, and when the new
one is current one +1 or -1, we retry using the _slow value.
Only when even the _slow suggests that the ambient zone has changed,

zone are permitted immediately.
