This PR is to address issue #483.

What testing has been done?

This is either a gap in our support for arrays of enumerations or some sort of issue with this specific function definition in the metadata. I want to say we have array of enums somewhere else in the API, so I think maybe the metadata is bad?

My point here is I don't think just no longer code-generating rosette is correct. I think there is a metadata problem.

I think rosette_meas_types = numpy.int32(rosette_meas_types) is generated based on get_instantiation_lines:

nidaqmx-python/src/codegen/utilities/function_helpers.py

Line 136 in a7a3643

instantiation_lines.append(

It has a special case for enum arrays, so yeah, I think the metadata for this parameter is wrong.
