I added saving and loading the neural network - The network saves to a .bin file with a desired path, saving space. In a previous project I made a while ago, I used JSON files, which grew very large. This will hopefully save space.
I made a new method in my util class. This helps convert a 1D array into a 2D one with a key, telling how many elements per layer. This will help when I switch over from hiddenLayersWidth and hiddenLayersDepth to an array of lengths.
