Request: Build ESP32 firmwares, along with FIDO+OpenPGP firmwares

[mcassaniti]

Hi. Thank you for your efforts so far. Can I request that you please automatically build:

• ESP32 based firmware
• Firmware that supports the fido2 branch (i.e.: FIDO + OpenPGP in one)

We have merged #7, which brings the pico-fido2 and pico-openpgp firmware. Next, we will begin working on the ESP32 build.
