feat: Add comprehensive tests for Advanced Compression API

- Test all compression parameters (levels, window log, hash log, etc.)
- Test all compression strategies (fast, greedy, lazy, btopt, etc.)
- Test reset functionality with different directives
- Test pledged source size functionality
- Test multi-threading parameters (nbWorkers, jobSize, overlapLog)
- Add validation for boolean parameters (must be 0 or 1)
- Fix ZSTD_c_checksumFlag validation to properly reject value 2
