[Bug]: (Dependency)pydub warnings on python-3.12

[mikewaters]

What happened?

Upon first use (fabric -h) on Python 3.12.3/darwin I received the following warnings:

/Users/mike/Develop/MeatAug/fabric/.venv/lib/python3.12/site-packages/pydub/utils.py:300: SyntaxWarning: invalid escape sequence '\('
  m = re.match('([su]([0-9]{1,2})p?) \(([0-9]{1,2}) bit\)$', token)
/Users/mike/Develop/MeatAug/fabric/.venv/lib/python3.12/site-packages/pydub/utils.py:301: SyntaxWarning: invalid escape sequence '\('
  m2 = re.match('([su]([0-9]{1,2})p?)( \(default\))?$', token)
/Users/mike/Develop/MeatAug/fabric/.venv/lib/python3.12/site-packages/pydub/utils.py:310: SyntaxWarning: invalid escape sequence '\('
  elif re.match('(flt)p?( \(default\))?$', token):
/Users/mike/Develop/MeatAug/fabric/.venv/lib/python3.12/site-packages/pydub/utils.py:314: SyntaxWarning: invalid escape sequence '\('
  elif re.match('(dbl)p?( \(default\))?$', token):
usage: fabric [-h] [--text TEXT] ...

This is an issue with the pydub dependency (pydub-0.25.1), which was fixed and merged a few years back but hasn't made it into pypi. Related issue: test failures on python 3.12

Attached is a patch to run against your Python 3.12 venv after installing fabric:

patch -i pydub-e9ce529.patch "/where/you/keep/code/fabric/.venv/lib/python3.12/site-packages/pydub/utils.py"

Obviously this is not under your control, and the Pydub project looks like it needs some love.

I haven't observed it impacting anything, so maybe it's a big nothingburger.
