AudioCache class
This class represents a cache for Local Assets to be played.
On desktop/mobile, Flutter can only play audios on device folders, so first this class copies asset files to a temporary folder, and then holds a reference to the file.
On web, it just stores a reference to the URL of the audio, but it gets preloaded by making a simple GET request (the browser then takes care of caching).
You can pre-cache your audio, or clear the cache, as desired. For most normal uses, the static instance is used. But if you want to control multiple caches, you can create your own instances.
