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!
