- Updated `hmm_cs` in `HMMERStep` class to use `Optional[str]`.
- Added a new function `has_cs()` to check presence of consensus sequence.
- Modified `view_alignment()` to handle `hmm_cs` correctly.
- Bumped package version in `pyproject.toml` from 1.0.0 to 1.0.1.
- Updated `hmmer-tables` dependency version in `pyproject.toml`.

These changes handle possible `None` cases for consensus sequences gracefully. 🚀
