Remove rootDelta branch
This makes rootDelta logic easier to understand, recalculating the value
where it belongs so removes an unnecessary branch.

Re: Stockfish
What is it? https://tests.stockfishchess.org/tests/ ... d5e27db0d8
Is this result even possible with so strong hardware or it means that something is now wrong with the scaling?
And of course it is not +1000 Elo but +104 what can be found in the details, but is is still a lot.

Add compensation factor to adjust extra time according to time control
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.

Wow ! This is not good...
”Latest Website-News (2024/06/02): Testrun of Stockfish 240526 finished: 0 Celo to Stockfish 240519, and sadly a measureable regression in EAS-scoring (nearly -20000 EAS points !)”
Thank you Stefan !
