dooly: update als lux equation and coefficient
Implement als sensor TCS3400 lux equation and coefficient:
Lux = DGFn * ((C * Ccoefn) + (R * Rcoefn) + (G * Gcoefn) +
(B * Bcoefn)) / (Atime*Again)
If (G+B)/C < 0.514, n=1
If (G+B)/C >= 0.514 and < 0.66, n=2
If (G+B)/C >= 0.66 and < 1.012, n=3
Else n=4:
Coeffs n=1 (Lo) n=2 (LM) n=3 (MH) n=4 (Hi)
Ccoef 3.8 -17.436 0.08 -0.686
Rcoef 3.956 14.535 -0.89 1.224
GCoef -20.915 32.07 7.096 4.043
BCoef 3.281 2.43 -5.603 -4.584
DGF 993 993 993 993
