As stockfish nets and search evolve, the existing time control appears to give too little time at STC, roughly correct at LTC, and too little at VLTC+. This change adds an adjustment to the optExtra calculation. This adjustment is easy to retune and refine, so it should be easier to keep up-to-date than the more complex calculations used for optConstant and optScale.
