New features for Okrolearn a machine learning library which is for powerful analzys and training while being light

Added suggesting architecture, optimisers are now used to update parameters, ranking networks, fixed some bugs, added GELU, softmin, swish, sigmoid, Mean Absolute Error, improved softmax. To my machine learning library like pytorch designed to have powerfull analyzys feautures while being lightweight. https://github.com/Okerew/okrolearn
