How to create Tensorflow 2 Sequence Dataset from scratch

Modern Machine Learning solutions require a huge amount of data, that's definitely the case when working with image recognition/object detection. Because of that, we need to create more and more complex datasets to teach our models. At this moment we cannot store the whole thing in the memory (sometimes even hard drive has a problem), quite often a description of that dataset is not directly readable by Tensorflow's Dataset. That's why we need to create a modern solution to handle and preprocess an enormous amount of data in easy to understand way using Sequences. Use Sequences to make datasets maintainable and fast.
