Sabaki 50.1 Hangs when Loading Some SGF Files

[MacErlang]

Hello,

I am attaching four sgf files that I downloaded from the web. The current version of Sabaki hangs
when I tried to load any of these files. However, all of these files open just fine in Sabaki 35.1. There are other files with similar issues. Possible bugs?

Best,
Shun

Extra spaces or empty lines in the file might have something to do with this issue.

The hanging of the file 珍珑棋局-1200手 - Original.sgf is of particular interest here: We use recursive functions to process all the nodes in a game tree and for some reason we hit the maximum stack size with gametree.getHeight() even though the game tree "only" has 3603 moves with only one tiny variation. Furthermore, it seems the game tree object of that file is so big that JSON.stringify() also hits the maximum stack size. This is now fixed.

@yishn WOW, thank you.
