Avoid crashing on Log File opening Stockfish crashes immediately if users enter a wrong file name (or even an existing folder name) for debug log file. It may be hard for users to find out since it prints nothing. If they enter the string via a chess GUI, the chess GUI may remember and auto-send to Stockfish next time, makes Stockfish crashes all the time. Bug report by Nguyen Hong Pham in this issue: This patch avoids the crash and instead prefers to exit gracefully with a error message on std:cerr, like we do with the fenFile for instance. Closes No functional change.
