Replace this with a CLI

[pistasjis]

I'm working on a CLI instead of using these bash scripts because it is a PITA to maintain. I'll probably try using the Crystal programming language, because while I'm a Go fan, the binaries Go produces are way too big, and Crystal looks quite easy to learn (other than the vastly different syntax) and the binaries it produces are quite small, and it doesn't cause a hole in your drive (which Rust does).

Every command will be in one binary, and it'll probably be more consistent, but what I know for certain is that it'll be easier to implement new features down the line.
