Allow image data

[kate-holdener]

The current version of the code does not work on image data. We want to add a feature that allows the user to use images as training and test data for their model. The pre-processing operations will be different than those done on the csv data.

This enhancement would be applied in the following ways:

1. Specifying the images directory where we have images of different classes.
2. Validating the images we have and removing any unnecessary/irrelevant images.
3. Preprocessing the images for getting the better insights.
4. Splitting the images into Train, Test, and Validation
5. Training the Deep learning model
6. Visualizing accuracy and loss of the model
