Use packaging to parse pandas version (#638)

* Use packaging to parse pandas version

Replaced manual splitting of pandas version string with packaging.version.parse for more robust version parsing. Added 'packaging' to project dependencies in pyproject.toml.

* Reorder import of packaging.version.parse

Moved the import of 'parse' from 'packaging.version' to align with linting guidelines.
