Second OpenPGP-card

[Valtteri Vuorikoski]

Some Javacards are available in at least larger SIM form factors. IIRC
the NXP J3H145 was available SIM-cut from Smartcard Focus at some
point, but it has been a while since I ordered one.

If it's an option for you to install an OpenPGP applet such as
SmartPGP (https://github.com/github-af/SmartPGP) on such card,
Javacards might be an easier avenue than cutting the official card.

I have a couple of NXP cards and SmartPGP appeared to work fine when I
tried it, but I mostly use them with a PIV applet so not sure about
the state of functionality with current (2.4-era) GnuPG versions.
