Moved user values to .env & added .gitignore

[saarmstrong]

Hey man, hope this is not too presumptuous but I wanted to ask how you would feel about some small QoL suggestions:

• Move the user specific values to a .env file that would allow the user to store their personal values without the fear of checking them in and publishing to github
• Added a .gitignore file to prevent myself (and others) from accidentally checking in their .env and generated pycache files

I am (impatiently) waiting on my e-ink screen to arrive, but I have tested this locally and I see the expected console logs as I saw when I ran the command on your main branch.

Not presumptuous at all, I'm glad to see someone improve upon my code. I reviewed your changes, and they look good. I'll clone the repo with your changes to my rpi and make sure everything works and then approve it. Thanks for your contribution!
