Subject: [PATCH net-next 10/11] tools: ynl: decode hex input

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>"}'
