Rs_pbrt v0.4.2 can render (some) Arnold scenes

I started working on a parser, which can use another renderers scene description (in this case Arnold’s .ass files). It's in a very early stage of implementation but it can be used on a couple of test scenes already. More about this in the release notes ...

I also worked on the parser a bit to be able to render a test scene from the Blender to PBRTv3 exporter. Look at the resulting image at the GitLab repository gathering test scenes for this Rust based implementation of PBRT. The .ass files for Arnold (mentioned above) can be found there as well.
