Package Extension for export to other medical imaging data formats

[nHackel]

Someday it might be nice to have an export to DICOM or NIFTI formats. We could realize that with a package extension on the respective Julia packages (and/or FileIO). In the main package we could then add an export/save function which checks the file ending and collects all implemented file extensions.

This way we can't add new export options outside of MPIFiles and have to manually update the export/save function but I'm not sure that we can rely on the other packages to always define a nice basic type to dispatch on

function export(mdf, file)
    extensions = filter(!isnothing, [Base.get_extension(MPIFiles, :MPIFilesDICOM), ...])
  
  # schaut welche matcht
  ext = ...
  
  # Export
  result = ext.export(mdf, file)
end

NIfTI has NIVolume and DICOM has DICOMData for dispatch.
