This is a quick release to fix a few bugs, including one pretty major bug for certain configurations.

Changes

• Fixed a bug introduced earlier in v1.4.x where in handicap games, or in even games where playoutDoublingAdvantage was set to a nonzero value, if pondering was also enabled at the same time, the search could sometimes contain values with different signs, greatly damaging the quality and strength of the search.

• Fixed a bug introduced earlier in v1.4.x where analysis with nonzero playoutDoublingAdvantage would use the wrong sign.

• For maxTimePondering, maxPlayoutsPondering, maxVisitsPondering, KataGo will now assume no limit (unbounded) if these values are not specified, instead of defaulting to using maxTime, maxPlayouts, maxVisits, respectively.
