XCAFDoc_VisMaterialPBR is missing properties in OCP 8.0.1

[bernhard-42]

I have built materials support for build123d with PBR support. In order to convert it to OCCT, I need XCAFDoc_VisMaterialPBR.
Unfortunately, the OCP 8 bindings for XCAFDoc_VisMaterialPBR are not complete. Missing properties:

• BaseColorTexture
• MetallicRoughnessTexture
• EmissiveTexture
• OcclusionTexture
• NormalTexture
• EmissiveFactor

Official Anaconda OCP 8.0.1 package:

Is it a regression wrt 793?

EmissiveFactor is, the textures not.
