[bug#60324] [PATCH 2/3] gnu: Add python-pyvisa.

[Vinicius Monego <monego@posteo.net>]

* gnu/packages/engineering.scm (python-pyvisa): New variable.
---
This package claims to be a Python interface to a library called "VISA" however I couldn't find such library. All the executable code in the repo is Python.
