[Cocoa] Now With Frame Caching!

What's new?
Basically it should be much faster as AMaZE demosaiced frames are stored in memory, and when a frame is requested it will either return a cached AMaZE frame, or bilinear if it has not been cached (for speed).

No processing or interface improvements, and user interface still leaking memory like crazy due to nooby usage of Apple's NSImageView, that is yet to be fixed, so restart the app every couple of minutes (if you wanna spend that long in it).

Realtime playback is almost there (still need to sort out adding more than one button to the ui however 🌚)
