Drive not mounted for UAC Admin

yes,kinda related. The current state is that the dokany volume is mounted only for the current user session. I don’t know how elevating user rights work, but i guess the elevated process is handled as another user and thus the drive will disappear. The fix would be pretty easy, we have to remove the mount option CURRENT_SESSION. But that would also impose a security risk, thus this should be optional.

This can be done in issue cryptomator/cryptomator#802 .
