Describe the request

The Arduino IDE allows customizing the default ino file with the arduino.sketch.inoBlueprint as mentioned here. It would be nice to have an equivalent version in arduino-cli when running arduino-cli sketch new. It may also be worth considering an option for a template sketch directory instead of just a template ino file.

Describe the current behavior

When running arduino-cli sketch new <project>, the same ino file with an empty setup and loop is created every time.
