Output and compatibility of Skip-Encoder.ipynb

[leon-bungert]

The run specification in block [11] should be checked. Furthermore, output shouldn't contain accuracies for a denoising task.

[TimRoith]

The previous skip-encoder notebook was not updated properly and was therefore not compatible with the major update
9e4a080.

The correct file was pushed in 3f3667b.

The accuracy output issue remains. Furthermore the notebook should provide the pictures from the paper.
