pdfsizeopt gets "DeprecationWarning: 'H' format requires 0 <= number <= 65535" [patch]

What steps will reproduce the problem?

1. python pdfsizeopt.py concen.pdf

I used the test file from issue 19
http://code.google.com/p/pdfsizeopt/issues/detail?id=19

What is the expected output? What do you see instead?

I get two deprecation warnings.  (The resulting pdf is ok.)
