cancerR 0.1.1

Bug fixes

• Fixed a critical regex bug in site_convert() that prevented correct conversion of ICD-O-3 topography codes with decimals.
• Improved robustness of aya_class() and kid_class() by ensuring site_convert() is always applied to the site input, allowing both numeric and character formats to work reliably.
• Fixed a typo in the error message for input length validation in kid_class().

Architectural changes

• Refactored shared classification logic between aya_class() and kid_class() into an internal helper function classify_internal() to improve maintainability and reduce code duplication.
• Replaced brittle magic numbers in matching logic with internal constants ERR_NONE and ERR_MULT.
