add hyperparameter search for convolutional model

Add simple fully convolutional network

rename hyperparemeter search as it seems to not work with MSE

add runs for first experiments

change hyperparmeter search to use MSE instead of MAE

rename experiments for focus 75

rename focus MAE experiment

reduce search space for optuna experiments

change logger to also use csv

add experiment to compare MSE and MAE (focus150.yml and focusMSE_150.yml)

add missing changes from original repository

cleanup to make ready as submodule
