* Move DwdWeatherWarningsAPI to a library hosted on PyPI
PyPI library uses new DWD WFS API
WFS API allows a more detailed query with reduced data sent as return
Change CONF_REGION_NAME from Optional to Required because it was never really optional
Set attribute region_state to "N/A" because it is not available via the new API
Add attributes warning_i_parameters and warning_i_color
* Use constants instead of raw strings
Streamline methods state and device_state_attributes
* Wrap api, use UTC time
* Update homeassistant/components/dwd_weather_warnings/sensor.py
