YES!

Day 1 of advent of code solved on the atari 2600!

It's only processing 1 line per frame so it takes ~81 seconds to complete, but I have tons and tons and TONS of scanlines to play with, so I can have a little refactor and be able to process multiple lines per frame.

I'd also like to display the number horizontally, currently I'm doing it vertically, doing it horizontal will teach me some "sprite" switching tricks.
