Description

This pull request adds support for the RetinaMNIST dataset to the project. It introduces a new dataset class, integrates it into the dataset registry, and provides comprehensive unit tests to ensure correct functionality.

RetinaMNIST dataset integration:

• Added a new RetinaMNISTDataset class in retinamnist_dataset.py, supporting loading, preprocessing, and combining train/validation splits for the RetinaMNIST dataset, with appropriate transformations and output shape handling.
• Registered RetinaMNISTDataset in the dataset_name_to_type_map in __init__.py to make it available for use throughout the codebase.

Testing:

• Added a new test suite test_retinamnist_dataset.py with fixtures and tests for initialization, data retrieval, tensor conversion, length, and output shape of RetinaMNISTDataset. Uses mocking to avoid external dependencies.
