Use 2 * bestMoveChanges. NNUE appears to provide a more stable eval than the classic eval, so the time use dependencies on bestMoveChanges, fallingEval, etc may need to change to make the best use of available time. This change doubles the effect of totBestMoveChanges when giving more time because the choice of best move is unstable.
