Deb packaging
Rework the packaging to use Debian native packaging instead of cpack.
Maintenance will be performed on git.ligo.org, containers.ligo.org, and docs.ligo.org on Tuesday 16 December 2025 starting at approximately 900 MST (1600 UTC). It is expected to take around 30 minutes and there will be several periods of downtime throughout the maintenance. Please address any comments, concerns, or questions to the helpdesk.
