Update Implementations of Metrics

[collinleiber]

• Update the implementation of multiple clustering metrics
• Fix error when using unsupervised accuracy with outliers Issue with Clustering Accuracy #106
• Fix errors when testing algorithms. First occured in Added SHADE #109
• Fix data loading issue by using fetch_file from sklearn
• Only test data loading functionality for one Python version to decrease necessary compute
