Add keyword_only_ignore_private configuration option

[mortenkrane]

Summary

This PR adds a new configuration option keyword_only_ignore_private to allow users to exclude private functions and methods (those prefixed with _) from the keyword-only parameter check (ODA007).

Key Changes

• Configuration: Added keyword_only_ignore_private boolean field to ProjectConfig class with a default value of False
• Checker Logic: Updated KeywordOnlyChecker._check_function() to skip private functions when the configuration option is enabled
• Documentation: Added configuration section to README.md explaining the new option
• Tests: Added comprehensive test coverage including:
  • Private functions checked by default
  • Private functions ignored when configured
  • Public functions still checked when private functions are ignored
  • Private methods ignored when configured
  • Explicit false configuration still checks private functions

Implementation Details

• The check specifically targets functions/methods starting with _ (but excludes dunder methods which are already skipped)
• The configuration is read from pyproject.toml under [tool.oida] section
• Defaults to false to maintain backward compatibility and existing behavior
• Works for both standalone functions and class methods
