More multiprocessing

[Johnnycyan]

Is there any way to make it use more cores? On my 3900x it only uses about 16% of my cpu. The default Photoshop PNG exporter uses the whole CPU. So I'm hoping this can be achieved to speed up the saving.

It should be possible to have the encoder split the frame into tiles that can be encoded on separate threads, but this would increase the image file size. The hard part would be developing an algorithm to guess the optimal number of tiles for a given image size.

I have noticed similar results on my 4790K, AOM does not always use the number of hardware threads that it is allowed to use when encoding a single frame without tiling.
