Add new "fast" filter for ambient light.

The slow filter wasn't converging fast enough when we shortened the
debounce timings but we still want it to ensure there's a long term
change happening, so add a new filter that converges much faster. This
new fast filter is just a weighted sliding window just like the slow
filter, but it has a significantly smaller horizon.
