Module codec 

Column codec trait and implementations for the binary cache format.

Each column type has a dedicated codec that exploits the statistical properties of that column’s data for compact encoding. All codecs implement the ColumnCodec trait.

See docs/binary-cache-format.md for byte-level format documentation.
