Revised spatial interpolation within dead pixel correction and added tests. Added pandas to conda requirements.

Revised interp_nodata_along_axis_2d (speeds up spectral interpolation by factor 40-50). Adedd numpy-indexed to dependencies.

Added config parameter 'enable_ac' (L2A contains TOARef instead). Revised file sizes in L2A XML file. Added ortho information to L2A XML. Bugfixes.

Added first version of L2A metadata to XML conversion. Further developed output writers. Revised paths getters.

Added Geometry_Transformer_3D (fixes issue #22). Fix for passing a negative viewing zenith angle to SICOR.

Fixed dead pixel map passed in the wrong shape to DeadPixelCorrector in case gapfill image is present.

Revised dead pixel map attribute and parts of DeadPixelCorrector (does not support 3D dead pixel maps yet).

Revised EnPT_Controller. Moved geolayer computation to L1B_Reader. Moved append_new_image() to EnMAP_Detector_SensorGeo. Revised append_new_image(). Replaced DLR test data.

Fixed conversion of DNs into radiance. Improved stdout of append_new_image(). Removed 'spectral' from dependencies. Fixed EnMAP_Metadata_L1B_SensorGeo.geom_view_zenith.

Added L1B_Reader compatibility with DLR test data format + test. Added RPC_3D_Geolayer_Generator. Removed imageio and lxml from dependencies.

Added test data for test_spatial_transform.py (fixes Test_RPC_Geolayer_Generator only running locally). Removed not needed DEM_Processor.to_map_geometry + test.

Added first version of Orthorectifier (does not yet transform all array attributes, misses metadata adjustment) + tests. Revised spatial_transform module.

Added first version of DEM_Processor + tests. EnMAP_Detector_SensorGeo.dem now contains a GeoArray with elevation data that is passed to AC. Moved Geometry_Transformer.isis_map_geo to geoarray.GeoArray.
