Update README.md

This dataset contains images of cellular automata generated using the [CellPyLib](https://github.com/lantunes/cellpylib) python library.

[Cellular Automaton](https://mathworld.wolfram.com/ElementaryCellularAutomaton.html) were described by Stephen Wolphram in [A New King of Science](https://www.wolframscience.com/nks/). Imagine you have a grid, like a checkerboard. Each square in the grid has a state - on or off, with the state of the square determining its color. There are rulesets (256 of them) that describe how the squares change their state depending on what's happening around them.
