TCEC-specific changes to UCI options

Below is a list of TCEC-specific changes to the UCI options compared to the upstream Cutechess.

Option name Description Changelog
UCI_Opponent The opponent rating field is set when the rating is defined in the opponent engine configuration. Otherwise, "none". Example line:
setoption name UCI_Opponent value none 3608 computer LCZero 0.27.0-pr1540ish-w_68653
Modified since S21. Before, "none" was always sent in the rating field
UCI_RatingAdv Rating advantage over the opponent. Sent only when the rating is defined for both engines. Positive numbers signify that the engine has higher rating than the opponent. This is intended to allow engines to play more/less aggressively based on the relative strength of the opponent. New since S21
