When doing a JPEG to JPEG optimization, we should never have an output image bigger than the input one.

If the guetzli+mozjpeg reencoding produce a smaller image → keep it
else, try a mozjpeg (lossless) optimization alone, and if it produces a smaller image → keep this one
else, just remove metadata and keep the original encoding.

Issue #43 must be resolved before this one
