Various bugfixes for search and training

This release is not the latest release, see newer release v1.13.0!

New Neural Net Architecture Support (release series v1.12.x)

The same as prior releases in the v1.12.x series, this release KataGo has recently-added support a new neural net architecture! See the release notes for v1.12.0 for details! The new neural net, "b18c384nbt" is also attached in this release for convenience, for general analysis use it should be similar in quality to recent 60-block models, but run significantly faster due to being a smaller net. For other recent trained nets, download them from https://katagotraining.org/.

What's Changed in v1.12.4

This specific release v.1.12.4 addresses a variety of small bugs or behavioral oddities in KataGo that should improve some rare issues for analysis, and improve the training data:

• Added a crude hack to mitigate an issue where in positions with a large misevaluation by the raw net that normally search could fix, if the search happened to try the unlikely move of passing, the opponent passing in response could prevent or greatly delay the search from converging to the right evaluation. Controlled by new config parameter enablePassingHacks, which defaults to true for GTP and analysis and false elsewhere.
• Changed the search to be more aware of the difference between computer-like rulesets that require capturing stones before ending of the game and human-like rulesets that don't in when the game end is triggered within variations of the search itself. This and the above passing hack are intended to address a rare behavior oddity newly discovered in recent KataGo versions in the last week or two prior to this release.
• Fixed a bug where komi was accidentally initialized to be inverted when generating training data from existing board positions where White moved first rather than Black.
• Fixed a bug where when hiding the history for the input to the neural net, the historical ladder status of stones would not get hidden, leaking information about past history.
• Fixes a bug in parsing the komi on certain rules strings (thanks @hzyhhzy)
• Updated the genconfig command's produced configs to match the new formatting and inline documentation for GTP configs introduced in an earlier release.
• Minor fixes and features for the tools for generating and handling hint positions for custom training.
