xlsxparser 0.11.0

//! Integration tests for Category 2 (異常系) against real, openpyxl-authored
//! `.xlsx` files that were then mutated the way a real-world failure would
//! corrupt them (truncated mid-write, a renumbered relationship ID, a
//! reversed merge ref) — see `scripts/generate_real_fixtures.py`'s
//! `corrupted_xml`/`missing_relations`/`invalid_merge_ref`/
//! `out_of_bounds_sst` for exactly what was mutated and why. Complements
//! `tests/error.rs`, whose fixtures are invalid XML from the very first
//! byte rather than a corrupted genuine file.
