Implement Audio API Object #18
Description
This is going to be relatively poorly defined at the moment, but want to allow users to play sound! Bevy is hopefully upstreaming a new audio API soon which is currently defined in the bevy_seedling crate.
A great place to start would just be allowing users to load and play one-shot sounds. But it'll be a fun task to define a more robust and high-level audio API for doing things like interacting sounds with animations.
