There are some hard limits in browser Canvas implementations, that will
throw a runtime exception when crossed. Since those limits are platform
dependent, the best we can do is catch it and back off from trying to
optimize a problematic file.
For example, a 60MB PNG can be processed fine by Chrome but Firefox will
fail trying to extract the ImageData from the CanvasRenderingContext2D
with NS_ERROR_FAILURE.
Also cleans up the media-optimization-utils and add post-resize size logs
