Day 10: Cathode-Ray Tube [AOC2022 Python]

I'm given a lines of instructions for a very simple computer driving a screen. It can call nop and add, where the add adds a value to a single register. This computer also has to keep a clock. I'll use the combination of the clock and the value to first find the value at a handful of given times, but then to create a display that will show 8 letters. I'll write a computer class with functions to handle the instructions and stepping.
