[diffoscope] Large layers in diffoscope docker image

Just discovered diffoscope and was giving it a try, but I was surprised to
see how large the docker image is:

$ docker run --rm -t -w $(pwd) -v $(pwd):$(pwd):ro \
      registry.salsa.debian.org/reproducible-builds/diffoscope file1 file2
Unable to find image '
registry.salsa.debian.org/reproducible-builds/diffoscope:latest' locally

   ]  210.7MB/1.212GB
045d07c7f1f1: Download complete
ba9a9e273802: Download complete

I considered opening an issue for this, but I thought I'd ask about it
first. I don't think 1GB+ image layers is a good idea. Was this necessary
for some reason?

Looking at the Dockerfile, I wonder if this could be remedied by combining
more of your RUN statements together:
