Issue with HEX payload

Hi! Thanks for the great tool.
I run into issue with hex-formatted payload.
If I select HEX and publish 0x00 or 0x64 it works fine, but if I publish 0xC8 it publishes 2 bytes. Today I tested the same payloads with mqtt-spy and it publishes HEX without any issue.
Many thanks in advance and greetings

Payload length

Hi, very usefull app. Thanks a lot!

But I catch an error when I'm using ws connection in payload length field.
5.2. Base Framing Protocol RFC 6455
Payload length: 7 bits, 7+16 bits, or 7+64 bits

Everything is ok, when payload length less then 7 bits, but when it's greater the second byte has wrong value:
>>> len(data)
141
>>> bin(data[0])
'0b10000010'
>>> bin(data[1])
'0b10000001' # here is an error because should be '0b11111110' for payload with 126 < length < 65535
