Add float waveform conversion methods and tests

[mjohanse-emr]

What does this Pull Request accomplish?

Changes were recently made to ni-apis to add new float waveform and spectrum types that will be used by the RF InstrumentStudio panels. This PR updates ni.protobufs.types to add conversion methods and tests for these new message classes:

• FloatAnalogWaveform
• FloatComplexWaveform
• FloatSpectrum

Why should this Pull Request be merged?

AB#3985023
AB#3985037

We need to expose these conversion methods via ni.protobuf.types so that the MDS python API can support the new types.

What testing has been done?

• Unit tests added
• Unit tests pass

Pull request overview

Adds float32 (single-precision) waveform/spectrum conversion helpers to ni.protobuf.types to support the new protobuf message classes introduced in ni-apis, and extends unit tests to cover these conversions.

Changes:

• Added float32 AnalogWaveform and ComplexWaveform conversion functions (FloatAnalogWaveform, FloatComplexWaveform).
• Added float32 Spectrum conversion functions (FloatSpectrum).
• Added/updated unit tests for the new float32 conversions.

File	Description
packages/ni.protobuf.types/src/ni/protobuf/types/waveform_conversion.py	Implements float32 waveform and spectrum <-> protobuf conversions.
packages/ni.protobuf.types/tests/unit/test_waveform_conversion.py	Adds unit tests for float32 analog/complex waveform conversions.
packages/ni.protobuf.types/tests/unit/test_spectrum_conversion.py	Adds unit tests for float32 spectrum conversions and renames some existing spectrum64 test names.

packages/ni.protobuf.types/tests/unit/test_spectrum_conversion.py:105

• This test currently asserts start_frequency/frequency_increment on the input spectrum rather than on the converted protobuf (float_spectrum), so it doesn't actually verify those fields are being set by float32_spectrum_to_protobuf.

    assert not float_spectrum.attributes
    assert spectrum.start_frequency == 0.0
    assert spectrum.frequency_increment == 0.0
    assert list(float_spectrum.data) == []
