Draft PR

The code is not complete, I would like to get feedback, please. If you are interested I will continue the development.

The lightweight Pneumonia MNIST dataset could be useful for beginners in supervised learning interested in training neural networks for biomedical applications.

Description

The PneumoniaMNIST is based on a prior dataset of 5,856 pediatric chest X-Ray images. The task is binary-class classification of pneumonia against normal. The source training set is split with a ratio of 9:1 into training and validation set, and use its source validation set as the test set. The source images are gray-scale, and their sizes are (384–2,916) × (127–2,713). The images are center-cropped with a window size of length of the short edge and resized into 1 × 28 × 28.
