Compared to version 2022-10-22, we are having 60 move rule and 3-fold repetition at root nodes that almost fully comply with 亚规 now. In addition to that, we also use the WDL model for score outputs and add all of these as tweakable UCI options for convenience.

The new compression architecture has been applied and a new arch net has also been released.
