Replace read_data with read_measurement_value and read_condition_value.

[mjohanse-emr]

What does this Pull Request accomplish?

Replaces the read_data method in the datastore-python package with these new read entrypoints:

• read_measurement_value
• read_condition_value

These read methods no longer uses the Moniker and MonikerClient to perform the read. It simply calls the lower level read_measurement_value or read_condition_value with the id from the PublishedMeasurement or PublishedCondition.

Tests and examples have been updated to use these new read methods.

All usage, documentation, and testing of Moniker and MonikerClient has been scrubbed from this python package.

I bumped the version to 2.0.0 since there are breaking changes to the read methods in this PR.

Why should this Pull Request be merged?

AB#3712177

We want datastore-python to use the new id based read entrypoints.
We want datastore-python to have similarly named read methods to the C# API.

What testing has been done?

All acceptance and unit tests pass.

I'm going to close this PR temporarily. Johann and I discussed an alternative that I'm going to try out, so I don't want y'all to waste time reviewing this in the current state.

Pull request overview

This PR updates ni.datastore’s read APIs to use ID-based gRPC read entrypoints (read_measurement_value / read_condition_value) and removes the Moniker/MonikerClient path, aligning the Python API with the newer service surface (and C# naming) while bumping the package to 2.0.0.

Changes:

• Replace read_data with read_measurement_value and read_condition_value, removing Moniker-based reads and related types.
• Update unit/acceptance tests, examples, notebooks, and docs to use the new read entrypoints.
• Update dependencies/lockfiles (drop moniker client, require newer measurements-data client) and bump version to 2.0.0.dev0.
