DICOM: wrong inversion for 16bit MONOCHROME1 when WindowCenter and WindowWidth are set

[ballaminut]

If a DICOM image:

• has a value for DICOM attribute (0028,1050) WindowCenter
• has a value for DICOM attribute (0028,1051) WindowWidth
• is MONOCHROME1
• has two bytes per pixels
  the values of bytes are modified in a wrong way.

IMHO this is due to a wrong calculation of the maxPixel value (line 415)

    long maxPixelValue = maxPixelRange + (centerPixelValue/2);

probably the intended calculation was

    long maxPixelValue = centerPixelValue + (maxPixelRange/2);

Hi @ballaminut , thank you for opening the issues and starting the investigation. Do you have sample files showing these issues which we could use for testing purposes?
