Enhance Selection, Viz & Automation

My objective is to enhance the Animint2 package through the introduction of new features, refining data visualization functions, reworking the code for dynamic data visualization, updating the testing suite, and resolving bugs. I have divided the project into several stages, beginning with the creation of fill_off and size_off functionality and moving on to the incorporation of GitHub Actions for the automated testing and deployment of the Animint book. Additional tasks involve relocating the update_axes computations to the renderer and developing the animint2pages function. Throughout the project, I will ensure proper code submission and testing by employing GitHub, unit tests, and continuous integration tools.
