PEP 621 metadata parsing

pep621 provides dataclass for PEP 621 metadata with support for core metadata generation. This project does not implement the parsing of pyproject.toml containing PEP 621 metadata. Instead, given a Python data structure representing PEP 621 metadata (already parsed), it will validate this input and generate a PEP 643-compliant metadata file (e.g. PKG-INFO).
