ordeq-iceberg: Add Ordeq Iceberg package

[Josersanvil]

Copilot summary

This pull request introduces a new Ordeq integration package for Apache Iceberg, named ordeq-iceberg. The package provides IO classes for loading Iceberg catalogs and tables, and includes supporting configuration, type hints, and a comprehensive test suite. The changes also register the new package in the workspace.

New Ordeq-Iceberg Package:

• Added ordeq-iceberg to the workspace and created its pyproject.toml with metadata, dependencies (including ordeq, pyarrow, and pyiceberg), build settings, test dependencies, and code coverage configuration. [1] [2]
• Added ordeq_iceberg/__init__.py to expose the main IO classes: IcebergCatalog and IcebergTable.
• Added py.typed file to indicate type hints are provided.

Core Functionality:

• Implemented IcebergCatalog as a dataclass for loading Iceberg catalogs, supporting both enum and string catalog types.
• Implemented IcebergTable as a dataclass for loading Iceberg tables from a catalog, handling both direct and IO-catalog inputs.

Testing and Examples:

• Added fixtures for setting up and tearing down test Iceberg SQL catalogs.
• Added unit tests for catalog loading and parameter handling in test_catalog.py.
• Added integration tests for table loading with both catalog objects and IO inputs in test_table_load.py.
• Added resource-based integration test and snapshot for loading a table, including logging and output verification. [1] [2] [3]

Pull request overview

This pull request introduces the initial implementation of the ordeq-iceberg package, providing integration between Ordeq and Apache Iceberg. The package enables working with Iceberg catalogs and tables through Ordeq's IO abstractions, with support for loading catalogs, reading tables, and creating tables with configurable behavior.

Key changes:

• Core IO classes (IcebergCatalog, IcebergTable, IcebergTableCreate) for Iceberg integration
• Custom error handling with IcebergIOError and IcebergTableAlreadyExistsError
• Comprehensive test suite including unit tests and resource-based integration tests
