Sun Position Calculator (CompassMesh) causes warning in packaged game due to being set to editor only

When packaging a project that is using the Sun Position Calculator plugin the logs will be spammed with warnings (Warning: Accessed None trying to read property CompassMesh). This could be worked around by using an is valid check for things that are referencing the compassmesh

1. Download the attached project
2. Open the project
3. Package the project
4. Run the packaged project
5. Exit running project
6. Open the logs file

Result: There will be a warning "Warning: Accessed None trying to read property CompassMesh"
Expected: There would be no warning (an is valid check could be used)
