fix(audiocontext): works on both Safari and Chrome

Fix for issue: #21

I'm not sure why the original code was so complex, but this simplified version seems to work on both Safari and Chrome on Mac OS.

const map: Map<string, AudioContext> = new Map();

export async function audioContext(options?: GetAudioContextOptions,) : Promise<AudioContext>  {
    if (options?.id && map.has(options.id)) {
      const ctx = map.get(options.id);
      if (ctx) {
        return ctx;
      }
    }

    const ctx = new AudioContext(options);
    if (options?.id) {
      map.set(options.id, ctx);
    }
    return ctx;
}

Yes, this is now broken on Chrome... More investigation needed.
