PRJ: Added support for Tektronix TDS3034B

[dschuechter]

Added support for the Tektronix TDS3034B oscilloscope incl. an example.

It shares the same device .yaml file as the newer Tektronix oscilloscopes. For that reason, some commands that work on newer devices might not be compatible with the old TDS3034B. Standard tasks like DAQ, configuration of the oscilloscope and so on are working.

Thanks! Can you have a look at the flake8 ?

[dschuechter]

flake8 is now fixed.

I will look after flake8 in future PR's :sweat_smile:
