Issue: create a command or Python function to write account data into the .env file

[BradKML]

Observing https://github.com/Altimis/Scweet/blob/master/Example.py#L33 it uses https://github.com/Altimis/Scweet/blob/master/.env to login and ger follow info. However, dotfiles are more likely to be inaccessible from some OS, e.g. Windows. Therefore it would be useful to have a terminal function to allow for the writing of data into the file, or from a Python function call, generate the dotfile from within the Python Terminal (or Python Notebook if one wants hell).
