Update to xpdf 4.06 source

[ReMiOS]

I've managed to compile the xpdf-python library with the new xpdf v4.06 sources from: https://dl.xpdfreader.com/xpdf-4.06.tar.gz
(for reference i've used Python v3.14.2, Windows 25H2 and Visual Studio with SDK 10.0.26100.0)

Unfortunately some headers have changed in the xpdf sources and i had to make some (nasty) changes
I've added False Boolean values and NullPointers to make it work.
This is not a correct fix, can you please help me fixing the xpdf-python the correct way ?

ImageDataDev.h

24: GBool listA, std::vector *imagesA) : ImageOutputDev(fileRootA, dumpJPEGA, dumpRawA, listA) {
==> GBool listA, std::vector *imagesA) : ImageOutputDev( fileRootA, dumpJPEGA, gFalse, dumpRawA, gFalse, listA, gFalse)
