add: batocera-info, user can manually add temperature sensors

batocera-info
- aligned script
- added "option" menu and a small help text
- users will see a list of thermal inputs by using --temp arg
- users can set the detected devices to HOME/user-thermaldev.txt

batocera-version, changes will be made later
