* Remove unnecessary copy operations: `Image.data` now always returns an immutable view of the original data. The
same holds for accessing meta attributes that are `np.ndarray`
* Change semantics of `ImageSequence.apply_image_data`: This method does not modify the original data anymore. Instead
it returns a copy of the original data
* Shorten too long image titles
* Do no override title for `CellImage` (fixes 2)
* Allow to disable clipping result of flat-field compensation
* Add pandas compability for Image meta
* Automatic extraction of meta data from image path
* Automatic scaling of image intensities using reference cell
* Hierarchical save based on image meta
