PGN comments may cause crashes in supervised training mode #131

Running on Windows 10 1709 x64. When parsing games with comments enclosed with braces, LCZero crashes. Preprocessing the PGN file with sed -i "s/ {.*}//g" games.pgn will circumvent the problem and output training data properly. It seems like a problem with LCZero’s PGN parser. Please investigate.

The PGN parser is very minimal, using a tool like pgn-extract is recommended.
