More thinking time after setting up a new position.

  • The time needed to set up the position after go came out of the time for the move in full. Setting up a position from scratch, from a FEN or by replaying the moves (e.g. after ucinewgame), takes much longer than entering a move (0.6 to 0.9 s for a FEN on an i5-1135G7), which left Psion hardly any time to think. Now at most 200 ms of the setup time comes out of the time for the move: Psion is told to move at setup + max(think - min(setup, 200 ms), 50 ms) after go. Normal moves are unchanged; after a FEN at 1+0, Psion reaches depth 7 instead of 5, at the cost of 0.4 to 0.7 s on the clock. The README's Time allocation section explains it.
