Describe the bug When attempting to use AssimpNet on ubuntu 22.04 LTS it fails to find libdl.so as the name has changed to libdl.so.2

AssimpNet has been updated to resolve this issue, so it would be appreciated if you could update the embedded assimpNet version.

To Reproduce Steps to reproduce the behavior:

  1. Run Unity Editor on Ubuntu 22.04 LTS
  2. Try and use URDF importer that uses the mesh importer
  3. Get DllNotFound error for libdl
