There is a HID gadget driver on Linux which provides emulation of USB HID devices. This could be very useful for testing the Solo firmware without actual hardware, using only a Linux box. This patch adds a command line argument which specifies whether the existing UDP backing should be used or the new one which reads and writes to /dev/hidg0. Testing done: 1. Created HID device with configfs 2. Started "./main -b hidg" as root 3. Successfully executed Webauthn registration and authentication on the same Linux machine Closes: #122
