Drivers for Valon 5015 Frequency Synthesizer instrument

[fedonman]

This PR:

• Adds the drivers/Valon/Valon_1505.py file which contains the driver for the Valon 5015 Frequency Synthesizer instrument.
• Adds the docs/examples/Valon_1505.ipynb file which contains an example on how to use the driver.

Tests and sims are not implemented, but the driver has been tested manually in the lab.

Amazing!! Can you add this driver in the __init__ of the drivers module? 🙏

@astafan8 can you take a look at this PR? We would love to merge it this week 😄

Hello @astafan8 and thanks for the approval. build docs action is failing with error ValueError: Could not locate a VISA implementation. Install either the IVI binary or pyvisa-py. I guess this has to do with the environment used in the action and not with the PR itself. But this error blocks the auto-merge feature, and there is no option for manual merging.

@fedonman ah, indeed. So one needs to disable the execution of the example notebook during the docs build, see here for instructions https://qcodes.github.io/Qcodes/examples/writing_drivers/Creating-Instrument-Drivers.html#Documentation

@astafan8 Done, thank you. Could you run the workflow again?

@astafan8 Hey, I think, GitHub doesn't like me and disabled the auto-merge 😆

If you feel everything is in place, be free to merge this. Thanks!
