fix(Reporting): use weighted average (with no_of_samples as weights) and only report level-1 OR level-2 model performance (#91)

* fix(Reporting): use weighted average (with no_of_samples as weights) and only report level-1 OR level-2 model performance

* chore(Config): updated sweep config

* fix(Reporting): missing import

* fix(Evaluation): get_first_valid_return_index can deal with zero valid indexes

* fix(Training): increase threshold for skipping assets

* fix(DataLoader): target asset should be always the first column
