v0.0.13

Changed

• The minimum Python version required has been brought back to 3.9
  (#64).

• The Attestation.verify(...) API has been changed to remove the Verifier
  argument in favor of an optional staging: bool kwarg to select the
  Sigstore instance
  (#62)

• The Attestation.verify(...) API has been changed to accept both Publisher
  and VerificationPolicy objects as a policy. The publisher object is internally
  converted to an appropriate verification policy.

Fixed

• python -m pypi_attestations verify now handles inputs like dist/*
  gracefully, by pre-filtering any attestation paths from the inputs.

• python -m pypi_attestations verify now exits with a non-zero exit code
  if the verification step fails
