IVI interfaces

[tobiasgehring]

Interfaces for oscilloscopes and AWGs following the IVI specifications. Wrapper for python ivi instrument library.

Description

The IVI foundation has published industry specifications for interfaces to various instruments. Here I define interfaces which follow these specifications and implement a wrapper to the python ivi instrument library. So far interfaces for oscilloscopes and AWGs are implemented.

This pull request is based on an earlier pull request which was reviewed by @a-stark. Since then I have improved the interface a lot. It is much more streamlined now and in my opinion easier to implement.

Motivation and Context

Qudi needs a standard interface for common instruments and the IVI specifications deliver such an interface definition.

How Has This Been Tested?

Using a Tektronix AWG5002C and a Keysight DSOS204A.
