Backup Wallet - Print paper wallet

NOTE: This option should only be shown under Settings -> Backup Wallet, and not needed to show at wallet creation phase.

On selecting "Settings -> Backup Wallet -> Print Paper Wallet" the user must be given a prompt to wirelessly print a PDF or equivalent formatted document.

The formatted document to be printed must show the steps to download, install, and restore the wallet seed phrase to either this iOS wallet or Android wallet (which we'll work on soon). For testing this feature we can go with this template to print:

Pirate Chain Wallet Backup - [DATE HERE]

Your Pirate Chain Address:
[ZS_ADDRESS HERE]

Seed phrase words QR code (Encrypted):
[24 SEED PHRASE WORDS QR CODE]

Ideally, I'd like the option to have a restore backup from some "encrypted" formatted of backup. This will allow having some sort of security if this printed paper wallet gets compromised.
If we decided on encryption method, then the restore wallet process needs to have the option to follow the process to enter decryption key.

NOTE: This decryption key MUST NOT be backup to iCloud keychain at any point.
