python-dpkg

• enable support on python 3.11, 3.12
• disabled support on python 3.7 (EOLed long since)
• update zstandard dependency
• various small build/test improvements, primarily migrating from black/flakeheaven/pylint to ruff

Pin included version of pycrypto/cryptography to address https://github.com/memory/python-dpkg/security/dependabot/4

• remove an extraneous print statement (contribution by @egerlach)
• stop importing print_statement from __future__ -- we dropped py2 support in v1.4 so the future is now

• bump PGPy to v0.6.0, which allows us to remove a pin to a now-deprecated version of pycrypto
• update to latest version of build-time tools
• remove support for python 3.7.0 and 3.7.1 (required by pylint)
• fix unnecessary-dunder-call issue flagged by pylint

• Pin back dependency on cryptography to avoid an unfixed ImportError upstream in PGPy.
• Drop support for Python 3.6, which is nine months past EOL
• various internal tooling fixes

This release adds support for zstandard-compressed control messages.

Massive cleanup release:

• deprecate python 3.4, 3.5
• support python 3.10
• update to latest PGPy
• clean up pgp signature validation logic that was dependent on a bug in PGPy <=1.4.1
• move to pyproject.toml and poetry for build management
• split init.py into modules
• many pylint fixes

This release fixes a longstanding bug in the comparison of versions that share a common root but where the first character in the longer version string is a tilde.

Add python 3.8 support; loosen six dependency.
