refactor: remove AuDD references and unused project files

Removed all files, dependencies, and mentions related to the AuDD API. Cleaned up the src directory, removing all non-developed or unused items, as part of a major cleanup. This change is due to the strategic shift towards using audio fingerprinting for song recognition, as opposed to sending the raw audio file itself.
