feat: Integrating AudioCenter into bones (#445)

Moved AudioCenter out of jumpy -> bones.

Reworked to remove the dependency on using a game's settings struct
directly + streamlining the interfaces such as having both play_sound
and play_music be super easy to use, with extra _advanced and _custom
methods for different levels of advanced features/usability on music.

Tested both music/sounds work.
