🔐 Single-Sig Spending Policies & 📱2FA!

You can now reconfigure your existing COLDCARD with a policy📑, so it will refuse to sign transactions that are too large, too frequent, or sent to an address not on your whitelist

We have also found a way to support **2FA authentication** using the usual phone apps (RFC 6238). If that's enabled, you will not be able to spend using your #COLDCARD unless you also have your phone and provide the correct #GoogleAuthenticator 6-digit numeric code.

Added file rename, Explorer is now offered for transactions of all sizes, NFC improvement, Added @BullBitcoin_, and many other fixes and improvements!
