Adding support for specific vendor HID command (0x41).

Browse source 
It is a self implementation, based on CBOR command.
data[0] conveys the command and the contents mapped in CBOR encoding.
The map uses the authConfig template, where the fist item in the map is the subcommand (enable/disable at this moment), the second is a map of the parameters, the third and fourth are the pinUvParam and pinUvProtocol.

With this format only a single vendor HID command is necessary (0x41), which will be used for all my own commands, by using the command id in data[0] like with CBOR.
