tuna: autobrightness: overhaul brightness table
Bump minimum from 16->19 since Prime ALS sensor reads minimum for a wide range of low light levels. Set second brightness bin just above minimum reading, to minimize the range of light levels that use the lowest brightness. Recalculate ALS/brightness curve so can add more points reasoably linearly (from Arve). Add many more brightness bins, avoiding steep cliffs of previous table.
