Grena3 solar position algorithm implementation.
This follows the no. 3 algorithm described by Roberto Grena of ENEA (2012).
The algorithm is designed for the years 2010 to 2110, with a maximum error of 0.01 degrees. It’s approximately 10x faster than the SPA algorithm but with reduced accuracy and time range.
