refactor: Leverage Parquet metadata to serialize failure info

[borchero]

Motivation

Due to the lack of support for adding metadata to Parquet files written by polars prior to polars 1.30, we're currently writing required metadata in a rather hacky way when serializing FailureInfo. With polars 1.30 introducing support for parquet metadata (pola-rs/polars#21806), we can streamline our logic.

Changes

• Use Parquet metadata to serialize rule columns of failure info
• Bump polars version requirement to >=1.30 (does this warrant a minor release?)
