feature request: add option to wipe target usb disk before installing image

[Seth Galitzer]

I use this tool a lot in my work environment to create install media, frequently reusing usb flash drives. As the image copy process just writes files to the disk, sometimes old files will prevent a new image from booting properly. I get the best results if I wipe the flash drive between each use, usually just running dd to write zeroes to the whole disk. But then I also have to repartition the drive and recreate the filesystem. It's a workable solution, but it takes time and adds an extra step to the process, and also adds extra wear and tear on the flash memory with the additional writes. If there was an option in the utility to maybe wipe the MBR and recreate the filesystem before copying files, that would be helpful.

Thanks for your consideration.
