- Updated `hmmer_tables/query.py` to import `Optional` from `typing`.
- Modified `hmm_cs` and `hmm_rf` to be `Optional[str]` in `Align` class.
- Adjusted `_parse_align_chunk` and `_merge_aligns_pair` for optional fields.
- Updated tests in `test_output.py` and `test_query.py` to reflect changes.
- Bumped version in `pyproject.toml` to 1.0.1 📦.

These changes enhance flexibility by making `hmm_cs` and `hmm_rf` optional, allowing for more robust parsing where these values might be absent. This update ensures cleaner and more reliable handling of alignment data.
