     * Let say you want to encapsulate a file type that is not defined in DICOM (exe, zip, png)
     * PNG is a bad example, unless it contains transparency (which has been deprecated).
     * It will take care of dispatching each chunk to an appropriate data item (pretty much like
     * WaveformData)
     *
     * Usage:
     * ./EncapsulateFileInRawData large_input_file.exe large_input_file.dcm
