Feature request: add a tab showing the incoming serial data like cutecom does that

[cedric-airsupplies]

I have a project that logs a series of values to the serial port in a format that's not "Simple binary", nor "ASCII". Therefore i need to specify the a custom frame.

It would help me a lot if I can see the data coming in from the serial port, in much the same way as cutecom does this: (i have redacted some of the incoming data, in reality there are more channels coming in)

I propose an extra tab in Serialplot called "terminal", with the raw incoming serial data, like in the below mockup:
