Updated Dockerfile for wider compatibility. Updated readme to use docker image in one command.

I couldn't get the docker container to run, tried to build one using the Dockerfile but it wouldn't work.
So, I fixed some dependencies and updates readme.md to customize the fonts with a simple docker command.

Just tried on fresh checkout of Fira Code -- it still works for me. What was the error you were seeing?

I can't get the image to build using the Dockerfile.

I figured this is because of FROM:python:3 which pulls latest python 3 image which is not compatible with some of the older libraries such as Pillow, request, urllib.
