PR Summary

This pull request refactors the installation instructions for R support in the README.md and README.pypi.md files. The previous method of installing R support using the validmind[r-support] extra has been replaced with a direct installation of the rpy2 package. This change simplifies the installation process for users who require R support.

Additionally, the PR includes several code improvements and refactorings:

• The MissingRExtrasError class in validmind/errors.py has been updated to provide a more accurate error message when rpy2 is not installed.
• The validmind/models/r_model.py file now includes a try-except block to handle the ImportError for rpy2, raising a MissingRExtrasError if the package is not installed.
• The validmind/__init__.py file has been reorganized to improve the structure and readability of the exported symbols.
• Several test functions in the validmind/tests directory have been refactored to improve code clarity and maintainability, including FeatureTargetCorrelationPlot, ContextualRecall, MeteorScore, ToxicityScore, MinimumROCAUCScore, and RegressionModelSummary.

The poetry.lock and pyproject.toml files have been updated to reflect the removal of the rpy2 dependency from the optional extras.

Test Suggestions

• Verify that the installation instructions in the README files work correctly for R support.
• Test the error handling in validmind/models/r_model.py by attempting to use R models without rpy2 installed.
• Ensure that all refactored test functions in the validmind/tests directory produce the expected results.
• Check that the reorganization of exports in validmind/__init__.py does not affect the functionality of the library.
• Run the full test suite to ensure no regressions have been introduced.

Awesome. Are these unrelated fixes required on the soon to be prod release?

Nope @cachafla these are just formatting/clean up of some of the raw data changes but not required.
