fix: azimuth setting of pvforecastakkudoktor provider (#567)

Browse Source 
EOS now enforces the general azimuth definition as e.g. defined in ISO 19111:
north=0, east=90, south=180, west=270. This is the convention that is and was
in the EOS documentation.

As the PV forecast of akkudoktor.net follows a different convention
(north=+-180, east=-90, south=0, west=90) the values from EOS are now converted
before the request is sent to akkudoktor.net.

BREAKING CHANGE: Azimuth configurations that followed the PVForecastAkkudoktor convention
(north=+-180, east=-90, south=0, west=90) must be converted to the general azimuth definition:
north=0, east=90, south=180, west=270.
