Add ability which can show the apparent temperature from a sensor

[oleg-d]

Fixes https://github.com/pkissling/clock-weather-card/issues/356

Allows you to specify a temperature sensor which can show the apparent temperature. This is something many weather providers provide and call it "feels like" or "real feel".

This brings it in line with the platinum-weather-card which has this feature.

just ran a test. looks good. just one question: should we apply the same rounding logic we have for other temperature values? i.e roundIfNotNull if show_decimal is false?

i could look into that in a few days
