Add APIs to work with a FPDF_PAGERANGE.
After getting a FPDF_PAGERANGE from FPDF_VIEWERREF_GetPrintPageRange(), one can now use FPDF_VIEWERREF_GetPrintPageRangeCount() to get the number of elements in the FPDF_PAGERANGE. One can then use FPDF_VIEWERREF_GetPrintPageRangeElement() to read the elements.
