What's new

Adding support for the Guardall/Verex/Chubb GProx II rfid cards.
This can read and clone the cards. But the algorithm for the calculated XOR and CRC bits is not currently known.
Based this off the Iceman Proxmark3 fork cmdlfguard.c and added displaying XOR and CRC.

Verification

I am able to read, emulate a GProxII card and write it to a T5577

@BarTenderNZ do you feel like this PR is ready to be merged?

Yes, I just made one last commit now so the comments don't fail the linting workflow so no longer having XXXXXXXX for the XOR Value.

Should now in theory pass all linting tests.

Edit. Just passed all tests. 🚀
