Adding Wind Direction and Dew Point to the Weather Plugin

[Circumnavigator-Gregg]

Perhaps wind direction and humidity displayed as dew point degrees could be configurable options in the default weather plugin. For now, I just added them locally to my code.

To add wind direction to my weather.py plugin, with degrees and cardinal text. For example:

   wind_direction = [" N", " NNE", " NE", " ENE", " E", " ESE", " SE", " SSE", " S", " SSW", " WSW", " W", " WNW", " NW", " NNW"]
    windy_deg = weather.get('current', {}).get("wind_deg")%360
    wind_index = int((windy_deg + 11.25) / 22.5)
    wind_cardinal = wind_direction[wind_index % 16]
    data_points.append({
        "label": "Wind Dir",
        "measurement": windy_deg,
        "unit": wind_cardinal,
        "icon": self.get_plugin_dir('icons/wind.png')
    })

and for Dew Point (which I find much more useful than relative humidity):

    data_points.append({
        "label": "Dew Point",
        "measurement": round(weather.get('current', {}).get("dew_point")),
        "unit": 'deg',
        "icon": self.get_plugin_dir('icons/humidity.png')
    })
