Add support for password safes

A password safe (PWS) stores names, logins and passwords in slots.  PWS
are supported both by the Nitrokey Pro and the Nitrokey Storage.  They
are implemented as a struct wrapping a device as the device may not be
disconnected while the password safe is alive.  The creation of a
password safe is handled by the GetPasswordSafe trait, implemented by
DeviceWrapper, Pro and Storage.
