More like the Klipper/Moonraker ecosystem

• The config file is moved to $HOME/.config/nfc2klipper/nfc2klipper.cfg, and has changed format to toml, looking like Klipper & Moonraker config files.

• Added a config file for moonraker (moonraker-nfc2klipper.cfg) to use its update manager for future updates of nfc2klipper.
