Test for ini parsing (python and C)

[aje-valeo]

Add tests for INI parsing.

• Python tests
• C test (inih library)
  • Using the local library (CMake assumes library exists)

Pull Request Overview

This PR adds comprehensive test coverage for INI file parsing in both Python and C. The tests verify that the configuration loading functionality correctly parses INI files, handles comments, and supports command-line overrides.

Key changes:

• Added Python unit tests for INI configuration loading with various test scenarios
• Added C-based tests using the inih library to verify INI parsing behavior
• Created GitHub Actions workflow to run both Python and C tests

All the if statements from lines 37-60 should be 'else if' statements. Currently, the logic continues checking all conditions even after finding a match, and the final 'else' block at line 61 only applies to the last 'if' statement (key7), not to the entire chain as intended. This means unmatched keys will incorrectly return 1 instead of 0.

This should assign to 'env_config->key31' instead of 'env_config->key3'. The current code incorrectly overwrites key3 when key31 is parsed.
