This patch add support for decoding hex input, so
that binary attributes can be read through --json.

Example (using future wireguard.yaml):
 $ sudo ./tools/net/ynl/pyynl/cli.py --family wireguard \
   --do set-device --json '{"ifindex":3,
     "private-key":"2a ae 6c 35 c9 4f cf <... to 32 bytes>"}'

FWIW, the hex can include spaces or not when using bytes.fromhex(). When
formatting hex for output, I chose to include spaces, but I don't really
know if that was a good choice or not.
