train model on colab after fixing normalization bug

remove secondary requirements (i.e. not things that are explicitly installed by the user), fix normalization problem, and use tqdm for image processing progress bar

Successfully configured the dataloader and trained for one epoch. Results are not so good, but it's something. Still the Fastaiv1 looked better qualitatively

Finished training of model, saving before qualitative testing. Seems model has actually learned something. Need to add metrics and params to the pipeline.

Finished data import and processing setup, bug in training step
