Custom image creator for raspios

Downloadable raspios.img file comes with default settings - including disabled ssh. A common way to customize the flashed OS is to use rpi-imager tool. This tool flashes OS directly to a removable device like USB or SDCard. Another way of enabling ssh is to simply put an empty file named ssh or ssh.txt onto rootfs partition of the *.img file containing raspios installation package.

TPi2 board requires either male-male USB cable (which I don't have) to access CM4 filesystem or to use tpi CLI for remote filesystem mounting (which did not work on Windows). Therefore accessing the filesystem directly after flashing it onto CM4 is out of the picture.

Last way to make CM4 accessible immediately after flashing was to modify the *.img file itself and put the aforementioned empty ssh file onto rootfs partition of the *.img file.

And this is exactly what the script does.

PS: I tested this on 2023-12-11-raspios-bookworm-arm64-lite only!
