Ni analog output

[alrik-durand]

Description

I've added a hardware module to interface a NI9263 4 channel analog output. Hardware is interfaced via the ProcessControlInterface interface.

Motivation and Context

Many experiment uses NI 6323 card with multiple functionalities. Analog output is one of them the card only have 4 analog output. The NI9263 can be used via USB or ethernet (depending of the module used for connection) and add more analog output.
Theses analog output are interfaced via the ProcessControlInterface.

How Has This Been Tested?

Tested with a NI9263 connected via USB cDAQ-9171 to a windows 10 computer.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Checklist:

• My code follows the code style of this project.
• I have documented my changes in the changelog (documentation/changelog.md)
• My change requires a change to the documentation.
• I have updated the documentation accordingly.
• I have added/updated for the module the config example in the docstring of the class accordingly.
• I have checked that the change does not contain obvious errors (syntax, indentation, mutable default values).
• I have tested my changes using 'Load all modules' on the default dummy configuration with my changes included.
• All changed Jupyter notebooks have been stripped of their output cells.

We don't have the hardware here in Ulm, basing only on the code no problem were spotted.

Is it necessary to set the analog output voltage to zero when deactivating the module?
I could see some usecases where it would be preferential to keep the voltage applied.

Well, of course we have the hardware. You can basically take any of the *insert arbitrary large number* NI cards in our labs.
