Curated catalogue for IRFundusSet (Integrated Retinal Fundus Set)

Integrated Retinal Fundus Set (IRFundusSet) is a dataset that consolidates and curates several public datasets to ease their use as a harmonized unit and to 
have a common definition of what is normal or healthy. 

Motivation: Existing retinal fundus public datasets do not follow a standard format or structure for organizing and archiving the datasets. Moreover, eyes/images marked as `not pathological` might represent healthy eyes or eyes with another pathology that is not relevant to the task or disease the dataset was created for. 

This dataset entails 

• A Python module that that consolidates and harmonizes the public datasets and that can be used in a  data pipeline following the PyTorch style for Dataset objects. 
• A curated catalogue in CSV format where images have been manually reviewed to determine if the image is of a healthy or pathological eye; a common definition for what is a healthy observation
