Winrate graphs in AI-analysed games; and sample NGD game review

Courtesy of Mikho, posts on this website now show rudimentary winrate graphs for ai-analysed games. This feature is still work in progress; there is a plan to also include KataGo scoreMeans in the graphs, as well as interaction between the graph and the sgf reader. Still, even now in this intermediate form, the graph should be a welcome …
