Issue #, if available: #128
Description of changes:
Adds DuckDB as a lightweight, JVM-free backend for PyDeequ 2.0 with optional dependency installation support. The overall design is inspired by DuckDQ project mentioned in #128 (actually most credit needs to go to that project). The stateful aggregation for streaming DQ monitoring is not implemented yet (i.e. MetricsRepository).
Other notable changes:
pyproject.tomlto support optional dependencies.pip install pydeequ[duckdb]- DuckDB backend (no JVM required). Core package now has minimal dependencies (numpy, pandas, protobuf)Engines.mdSee https://github.com/awslabs/python-deequ/blob/v2_engine/README.md and https://github.com/awslabs/python-deequ/blob/v2_engine/docs/architecture.md for more background.
