Feature wishlist

[langestefan]

The following features are planned:

• Full benchmarking of both performance and accuracy to enable a more informed choice of solar position algorithm for a given application.
• Implementation of remaining solar position algorithms that appear in solposx and pvlib.
• Add support for multithreading. This can be implemented at the interface level, so all algorithms can benefit.
• Add guide to implement a new solar position algorithm, explaining the interface design.
• Add extension for ModelingToolkit.jl. There needs to be a way to integrate solar position functions (azimuth, zenith) into a ModelingToolkit.jl model. Example name: SolarPositionModelingToolkitExt.

(maybe):

• create a StructArray type for many observers, one datetime.
