A small utility to send a reboot request to a Raspberry Pi Pico.

Uploading code to a Pico board involves resetting the board by plugging the USB cable while holding down the boot button. This can be annoying for quick compile-upload cycles and can be stressful for the hardware itself.

The Pico standard library can, if enabled, respond do a reboot request via USB and reboot the device in either flash mode, just rebooting the device to the currently uploaded app, or in bootsel mode, to boot into the boot loader, akin to plugging the Pico while holding the 'boot' button.

Note: The reboot request handling is opt-in, and requires the pico application to be properly setup for it. Check the Pico SDK documentation for more information.

Additionally, the Pico bootloader does not handle reboot requests, so if the device is currently in bootsel mode (you can see the USB media for uploading .uf2 files), the reboot request will not be handled, and no reboot occurs.

By default, invoking the command will issue a request to boot to bootsel.
