SUGGESTION: raw hexadecimal message viewing and editing

[ryangriggs]

Some MQTT messages are more efficiently encoded as a byte buffer (i.e. integers, floats, etc) instead of a string. It would be great to have a view/edit feature for such messages that displays the message as a sequence of bytes in hex format, which can be viewed and edited (published) easily. While the app already has the "raw" option, it's not easy to read and edit raw byte data.

Thanks for a great app!

+1. I have a use case where we are sending raw measurement data from microcontroller and ability to read/send hex data would be amazing.
