Add an Example for MLP usage on fractality Dataset

[Samyssmile]

Actually, we demonstrate the usage of our MLP implementation only with an MNIST dataset, which is a byte dataset. Add a new example that showcases how it works with PNG files

For orientation look at FractalityNetworkTest.java.

Path for new Example Java File.

example/src/main/java/de/example/mlp

Missing File

ImageClassificationExample.java

Dataset

Use the dataset from:_ lib/src/test/resources/fractality
