Initial Setup is *very, very* weird

there needs to be a .env file, but that's to setup pygmentise theme and path of python (in case you're using a venv/conda env). You also need to run `npm install` the first time, then run `pip install -r requirements.txt` and then begin running mettu.

Very, very complicated.

Can be fixed by having a "Setup" script of sorts or maybe running `npm run dev` should trigger the pip install command, but keep in mind that it has to be performant.

Also make the .env file more useful, like maybe the daisyUI preset themes and what not, but again, this is bonus.
