Previously deserializing assumed that open_blocks had enough capacity to deserialize all blocks. It appears that this is not always the case and that open blocks can overflow.
This commit will realloc s->open_blocks if the current capacity is not big enough.
Fixes #114
Fixes neovim/neovim#25164
Note that I tested this on my machine with the steps/file that reproduces a crash in neovim/neovim#25164 and it worked reliably.
