Fix typos in comments and documentation

[maxtaran2010]

Fix minor typos found by codespell in docstrings and inline comments across the source files:

• homogenous → homogeneous (in docstrings and comments in cols.py, converters.py, _compat.py)
• heterogenous → heterogeneous (in docstrings and comments in cols.py, converters.py, gen/__init__.py)
• overrrides → overrides (comment in converters.py)
• sublcasses → subclasses (docstring in strategies/_subclasses.py)

No functional changes - only comments and docstrings were updated. Public API names (e.g. homogenous_tuple_structure_factory) were intentionally left unchanged for backwards compatibility.
