Referenced nuget package AssimpNet on Linux looks for libdl.so instead of libdl.so.2

[jskripsky]

On modern Linux distros, the dynamic loading of libraries is handled by /usr/lib64/libdl.so.2. AssimpNet, the .NET wrapper for AssImp, is rather old and still has the binary's name "libdl.so" hardcoded (see here).

This leads to the following exception at start-up:

System.DllNotFoundException: Unable to load shared library 'libdl.so' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibdl.so: cannot open shared object file: No such file or directory

To work around the problem, just create a new symlink libdb.so pointing to libdb.so.2 as suggested here:

It seems like I broke this when I renamed Aardvark.SceneGraph.IO to Aardvark.SceneGraph.Assimp but forgot to move this file: https://github.com/aardvark-platform/aardvark.rendering/blob/master/lib/Native/Aardvark.SceneGraph.IO/remap.xml

I fixed this in the master branch but if you're using old Aardvark.Rendering packages (>= 5.2 and < 5.5) this was not the cause of your issue.
