Thanks Jose!

It seems that there is an agreement that a --force option would be
useful. When passing this option, the data on the device will be
destroyed with 'wipefs --all'.

Most likely the option will be called --destroy-existing-data so that
users are warned about the potential danger of using it.

I'll have a look at implementing this.
