[Paraview] Export X3D Files via Python >version 3.8

[Andrea Beck]

Hi everyone, hi Sebastien,
I have a follow-up question about the exporting of X3D files via python. 
I noticed that the X3DExporter (see code below) works fine, but creates 
only ascii- X3D files, not the binary ones (*.X3Db). The binary export 
is available through the GUI, so I'm pretty sure there must a python way 
of doing it. I tried some obvious first guesses (renamed 
exporters.X3DExporter(FileName="foo.x3d") to 
exporters.X3DBinaryExporter(FileName="foo.x3d") for example ) , but 
couldn't find a way to do it. Is there some easy way to export as binary 
x3d, instead of ascii?

Thanks for reading, best regards
Andrea
