Code Review
This pull request introduces a new Delta Lake IO module for the Java SDK, including dependency configurations, the initial DeltaIO class with a ReadRows transform skeleton, and unit tests. Feedback suggests improving the DeltaIO builder by marking setTablePath and the withConfig parameter as @nullable for consistency. Additionally, it is recommended to perform a defensive copy of the configuration map to ensure immutability and to consider renaming withConfig to withHadoopConfig for clarity.
