Add sun event scheduling (e.g. RunAtSunrise() )

[duanemck]

Proposed change

In home automation it is often useful to trigger automations based off sun events such as sunrise or sunset. This feature extends the scheduling extension and wraps the SolarCalculator Nuget library to add a service with methods such as RunAtSunset(). I've only added sunrise, sunset, dusk and dawn though the underlying library supports other events.

As the SolarCalculator requires latitude, longitude and a Solar calculator to work, the new methods could not be added as extensions methods on IScheduler, so instead, a new service was introduced.
