We were using a very old version of this library that broke with
Python3.12. This updates to a Python 3.12 compatible SHA.
The specific breakage at the former commit was that
`collections.Hashable` was deprecated and moved to
`collections.abc.Hashable` in Python 3.7. It was removed in Python 3.8.
For anyone on newer versions of Python3, such as Python 3.9.6 which
ships with macOS 15 Sequoia, this is broken.
The error on versions of Python newer than 3.8 is:
```
