Export Eiger pixel mask window

The Export Eiger mask window is fairly simple as it only allows to export the Eiger detector-internal pixel mask for dead and defunct pixels as an image.

The first Parameter allows to select the _master file from the data acquisition with the Eiger detector. Because the internal structure of these files is always identical, there is no need to specify the Hdf5 dataset.

The second Parameter is the filename for the export. Any format supported by pydidas can be used for the export.

After setting both Parameters, use the Export pixelmask button to write the mask file.
