Details:

Sometimes it is helpful to know the number of cases in a .sav file.  For
example, in loading large files, it is good to be able to show progress to the
end user.

But right now, there is no way to get the total number of cases, other than
scanning through all the records, which can be slow for large files.  So this
request is to add a new method like "get_num_cases", which could be called
like this:

   my $pspp = PSPP::Reader->open($file);
   my $case_count = $pspp->get_num_cases();
