Encodes the ILcdModelReference that is associated with a data source.
Some formats do not include information about the coordinate system that is used in their data files. For these
formats, an additional model reference file may be placed next to the data file, providing information about the
coordinate system. ILcdModelEncoder implementations for these formats often allow to configure an
ILcdModelReferenceEncoder on them, which is capable of encoding the model reference in a reference file,
next to the data source.
