Joseph Doherty 6e7bcadf68 feat(etl): implement TransformingDataReader and DataTransformerBase 
Add core transformer infrastructure for the ETL pipeline:
- DataTransformerBase: abstract base class with virtual methods for
  field count, names, types, values, ordinals, and null checking
- TransformingDataReader: IDataReader wrapper that delegates to
  transformer, enabling on-the-fly data transformations
