v2.3

What's Changed

• Add hash128, which returns a 128-bit signed integer.
• Fix a misplaced operator which could cause memory leak in a rare condition.
• Fix a malformed value to a Python/C API function which may cause runtime errors in recent Python 3.x versions.

The first two commits are from Derek Wilson. Thanks!
