Option to unmount disks automatically

[DumbGameMaker]

Is your feature request related to a problem? Please describe

With default system settings on my os (arch/kde, but probably others), disks get automatically mounted when detected. However, this can conflict with WoeUSB, because sometimes the disk will get mounted while creating the disk.

Describe the solution you'd like

add a -f/--force flag, which will unmount partitions automatically before doing anything that needs it unmounted

Describe alternatives you've considered

People could disable the setting manually before creating, and reenable afterwards. This is kinda a pain though, and people might not want to be bothered or may not think of this being the issue
