Minor Update
New Features
`BlockUnion`: Introduced a new feature `BlockUnion` which outputs a pandas DataFrame. This functionality enhances the `sklearn` `FeatureUnion` processing capabilities by allowing users to combine multiple data blocks into a single DataFrame instead of using `hstack`.
Patch Update
Enhancements
`BaseTransformer`: Added a fit method to the `BaseTransformer` class. This patch improves the extensibility of `BaseTransformer`, enabling it to be more easily integrated with other components (e.i. `Pipeline`) that require a fitting process.
