Dies on scrambled .puz files

This prevents scrambled .puz files from loading on downforacross.com

Here is a sample puz file that won't load:

Yes. It opens fine in other apps. In fact I used puzpy to remove the scrambling and then opened it in downforacross.

This library throws an error if the solution is scrambled. The library should either implement descrambling like pypuz or (much easier) just treat it like a .puz without solution data.
