Initial commit of code for calculating sun position
Given the longitude and latitude, and a time into 2024, calculate the relative sun
position suitable for providing lighting angles.
Based on code from https://www.psa.es/
Loosely checked against https://www.pveducation.org/ and its close, working on faith
really, but the numbers look plausible.
Could do with a tidy up!
