Module manifest 

Manifest file handling and data file tracking for Iceberg tables.

This module provides the core types and implementations for working with manifest files, which track the data files that comprise an Iceberg table. Key components include:

• ManifestEntry - Entries tracking data file additions and deletions
• DataFile - Metadata about data files including statistics and metrics
• Content - Types of content stored in data files (data vs deletes)
• Status - Tracking additions and deletions of files
• FileFormat - Supported file formats (Avro, ORC, Parquet)

Manifest files are a key part of Iceberg’s architecture, providing metadata about data files and enabling efficient file pruning during queries.
