Add new YUV converter with avg color calc (#287) 
Add new YUV converter with 2x2 pixel matrix YUV color estimation.

The new YUV color converter, as opposed to the original one, uses more precise color calculations based on four neighboring pixels' average color values which helps a great deal with image aliasing / shimmering artifacts.
By default, it runs in the multithreaded mode with the game frames sliced between 2*(CPU cores) goroutines.
In case if this estimation mode doesn't work as expected it is possible to switch back to the original mode.

The default encoder is switched to x264 since it's faster now.
