expand u2f-zero to include OpenPGP #75

How do we expand this project to include OpenPGP capability? If Yubikey can include OTP+OpenPGP surely u2f-zero can include an OpenPGP version either separate, or integrated with the existing device.

It wouldn't be feasible with the current version of U2F Zero since there's only 16 KB of program memory and most of it is used already for U2F application.

A future version could do this but the microcontroller would have to be upgraded. I just created #76 for this.
