In ces: Access to Canadian Election Study Data

ces 1.0.2

Bug Fix

• MAJOR: Fixed critical bug in create_codebook() function that caused "arguments imply differing number of rows" error for multiple datasets (2015 web, 2015 phone, 2021 web). The issue was caused by multi-value variable labels being incorrectly handled, leading to vector length mismatches during data.frame creation. Multi-value labels are now properly collapsed with " | " separator.
• Added comprehensive tests for create_codebook() function to prevent regression, including specific tests for multi-value labels, missing labels, and different output formats.
• Verified fix works across all CES datasets and maintains backward compatibility.
