Description: Provides a set of convenient functions for calculating
        sun-related information, including the sun's position
        (elevation and azimuth), and the times of sunrise, sunset,
        solar noon, and twilight for any given geographical location on
        Earth. These calculations are based on equations provided by
        the National Oceanic & Atmospheric Administration (NOAA)
        <https://gml.noaa.gov/grad/solcalc/calcdetails.html> as
        described in "Astronomical Algorithms" by Jean Meeus (1991,
        ISBN: 978-0-943396-35-4).
