My Nand2Tetris Work

I’ve been going through nand2tetris for fun and self study.

Note: I may have accidentally encountered some data loss of some select files from the last couple of months, including the previous project directory for my nand2tetris progress. As such, there will be a bunch of commits close together as I re-do chapters 1-4 from sketches I made on a notebook (except chapter 4, where I forgot to draw out the flowcharts for each assembly language program).
