Dyson Sphere Stress System

Overview
This is the only Technology that has multiple levels to research. There are 6 levels total.
Each level gives 15° extra Build space on a Dyson Sphere, starting from its equator and measured in both directions. (For example, the first unlock provides 15 degrees above and 15 degrees below the equator, for a total of 30 degrees latitude buildable area.)
