Added Support for HmIP-SWO-PL
Added Support for HmIP-SWO-PL

I manually edited the sensors.py on my system to get my "HmIP-SWO-PL" working in Home Assistant. 

It is nearly the same as the "HmIP-SWO-PR": IPWeatherSensor which is already supported with pyhomematic just without the wind direction sensor.

The two values for "WIND_DIR" and "WIND_DIR_RANGE" now show "false" as value. Maybe there is a smart way to not create those sensors if they are not available?
Thx
