    Set permissions on user_secrets.yml to 0600

    The permissions on the user_secrets file are too open, adjust this so that
    after using pw-token-gen.py it sets the file to be 0600 for
    user_secrets.yml and the backup tar file that is created. Additionally,
    add a note in the README to recommend adjusting the permissions when not
    utilising the pw-token-gen.py
