Add azimuth as state to sun.sun

It would be great if the sun component also had current azimuth and not just elevation. This would make it possible to close/open sun screens when the sun is within certain angles of the house.

Wow, that was fast. Thanks!!! This has just saved me from having to install 3 light sensors for different angles of the house and just have one common brightness sensor :smiley:
Thanks, Fabian

So far it is just a PR.

Will be available with 0.21.
