Bug#963551: python3-bitstring: Update, DeprecationWarning

[Matthias Urlichs]

Hello Graham,

>> There is another problem: broken backslash sequences trigger a

> Would you please provide the steps to reproduce this issue?

Correction: only if you tell it to treat all deprecation warnings as
errors, which some packages do in their test runs.

$ cat t.py

import bitstring

$ pytest t.py
