Enable Passphrase for Restore Command

[Psifour]

Description

Implements an option to pass a passphrase when restoring from mnemonic.

Related Issue

Closes #1671

Motivation and Context

Without this change users are only able to (easily) import a wallet from Sparrow if they did NOT use a passphrase.

How Has This Been Tested?

Default case has been verified to call to_seed() with no passphrase and all single word data passed with the option is verified to replace that. Utilizes the standardized behavior as seen in other sub-commands.

I've already done the create command changes, but have not implemented unit tests. Will try to get my work committed tonight or tomorrow on this.
