Time management improvements 1. Tune time management parameters. 2. Scale the optimum time and maximum time parameters based on the amount of time left, using a logarithmic scale. Many acknowledgements to @FauziAkram for tuning the parameters and for the original idea (see https://tests.stockfishchess.org/tests/view/652f0356de6d262d08d333c5).
