Databricks Delta Live Tables (DLT) Python Stubs

The `databricks-dlt` library provides Python stubs to facilitate local development of Databricks Delta Live Tables (DLT) pipelines. It offers API specifications, docstring references for IDE autocompletion, and Python data type hints for static type checking. This library is purely for development-time assistance and *does not contain functional implementations*; DLT pipelines must be executed on a Databricks workspace. The underlying DLT product has recently been updated to Lakeflow Spark Declarative Pipelines (SDP) by Databricks, with continuous updates on the platform.
