<![CDATA[New Layer: Heat Index]]>We already have layers for Heat and for Dew Point.

The "Heat Index" is much more intuitive to most users. Please provide this new layer calculated as:

First, get
RH (relative humidity, %):
es = 6.112 * exp(17.67 * T / (T + 243.5))
e = 6.112 * exp(17.67 * D / (D + 243.5))
RH = 100 * e / es
T = air temperature (°C)
D = dew point (°C)

Then heat index (HI, °C):
HI = -8.784695
1.61139411 * T
2.338549 * RH
0.14611605 * T * RH
0.012308094 * T * T
0.016424828 * RH * RH
0.002211732 * T * T * RH
0.00072546 * T * RH * RH
0.000003582 * T * T * RH * RH”

These RH and HI formulas are standard Magnus-type humidity and heat-index polynomials in °C.

I'm guessing US users' preference settings for Fahrenheit will handle that conversion?
