Update TrezorDevice's `isUsedElsewhere` & `unacquired` properties

- both properties are now deprecated
- following properties are now used instead (matching trezor-connect):
 - `type` with possible values `acquired` | `unacquired` | `unreadable`
 - `status` with possible values `available` | `occupied` | `used`
