it is possible to print uint8 array as hex values

[MicheleBe]

Hi it is not an issue, but more or less a feaute that will be nice to have, It is possible to export with --json flag uint8 array als equivalent hex values ?

sometimes like string << "0x" << std::setfill('0') << std::setw(2) << std::hex, overloading the print method?

Thanks a lot
cheers Michele
