[PRQ#45816] Merge Request for audacium

MarsSeed [1] filed a request to merge audacium [2] into tenacity [3]: I propose this package merge, as Audacium upstream has announced in Jan 2023 that they officially merged with the Tenacity project and repo. [a] The Audacium repo has been archived since. [a] AUR users should be well-informed now, as @dreieck was kind enough to mention this change in a comment in Feb 2023, and his comment is the last one on the AUR/audacium page.
