Performance issues

[uuttff8]

I've been reported that this library is much slower than https://github.com/hyperoslo/Cache, just my experience

Hi @uuttff8, thank you for raising this concern. I was thinking of picking this project back up again, as it needs a bit of work. Do you have any suggestions on how to improve it? Thanks.

Hi @asowers1, I think, to do perfomance issue done, you should introduce RAM Memory Cache (such as NSCache) for short-term objects, and Disk Cache for long-term objects, of course Codable objects, finally combine it into HybridStorage as it done here. Also introduce async version of saving objects, and exclusive feature should be Typed Errors in Async, that is must have for me.
