Return image buffer instead writing to output

[Timmimim]

Hello there,

I am currently developing a tool that will automatically extract images from an HTML document as Buffers, compare them, and create a 'diff-document' containing the output images from a blink-diff comparison of images with equal index.

For performance reasons, it is not optimal for me to have blink-diff write .png-files, only for me to read them as Buffers again.

However, I am for a while now failing to find a way to return the Output-Image as a Buffer, or in any way get an output convertible to such.
Can you help me with that? That would be very much appreciated!

Kindest regards in advance, Timm Kühnel

This would be very helpful. I also noticed the output.js uses writeFileSync to actually write the file. Is there a reason this is not done async?

@Timmimim I just went ahead and forked it and made the necessary changes.

Here is the PR: https://github.com/yahoo/blink-diff/pull/44

Hope this helps
