Princhess 0.10.0

https://github.com/princesslana/prinche ... tag/0.10.0

Too fast for me, haha.

Changes:
* Chess 960 Support
* New network and policy, adding the 2500+ rated lichess games (Thanks Dann Corbit)
* NPS improvments
* Bug fix in PV

Only ran a short self play since it's not gonna produce a particularly useful figure:

Code: Select all

Score of princhess-0.10.0 vs princhess-0.9.0: 79 - 15 - 6  [0.820] 100
...      princhess-0.10.0 playing White: 42 - 6 - 2  [0.860] 50
...      princhess-0.10.0 playing Black: 37 - 9 - 4  [0.780] 50
...      White vs Black: 51 - 43 - 6  [0.540] 100
Elo difference: 263.4 +/- 87.9, LOS: 100.0 %, DrawRatio: 6.0 %
