pip-audit 2.4.9

Release 2.4.9

on Python PyPI

[2.4.9]

Fixed

• The --output flag will no longer produce an empty file in the event
  of a failure within pip-audit itself, making it easier to distinguish
  between audit failures being reported by pip-audit and pip-audit's
  own errors (#432)

• Removed pin on packaging now that our dependency pins it for us
  (#429)
