refactor main to use YAML parser and test with personal twitter bot

[erikkristoferanderson]

👨‍💻 Changes proposed

factor main and load_env plus just print for now

We can't use tweepy.API, because the twitter bot account is only allowed to use twitter API v2, which is compatible with tweepy.Client(). Also the loadenv file needed to be refactored because it wasn't working. Also changed the logic in main.py to suit the new reminders.txt format. Also created an example .env-example file to show the shape of what the .env files needs to be, and added .env to .gitignore.

With bearer token, I attempted to run this, and the error was: tweepy.errors.Forbidden: 403 Forbidden

I will refactor this using the Python yaml parser.

The bot does send tweets, with my personal bot credentials. See here: https://twitter.com/odes_erik_bot/status/1528828488878284800
