Merge dev branch into master.

New features / improvements:

• Added a lot of software tests
• Added output writer for EnMAP Level-2 data
• Added metadata class for EnMAP Level-2 data
• Revised dead pixel correction (now 40-50 times faster; added spatial interpolation)
• Added support for dead pixel correction based on 3D dead pixel maps
• Added orthorectification module
• Added support for 3D (band-wise) geometry layers
• Added 3D geolayer generation based on band-wise RPC coefficients.
• Updated L1B reader to match DLR L1B format
• Added subsets of official DLR test data
• Improved DEM processor (added overlap and geographic datum check)

The current version provides a working processing chain from L1B to L2A for the official DLR L1B data.
