Add the ability to send HEX values for the TCP Sensor

The ability to write a HEX value to the payload field for the TCP sensor is badly lacking.
Is there any way to send TCP packet whith payload fild contains \0x13\0x13\0x00\0x01 in hex format, not string?
For example like this:

sensor:
  - platform: tcp
    name: TESTING_TCP
    host: 192.168.74.48
    port: 20105
    payload: "\x13\x13\x00\x01"

Doesn’t that actually work?
