ModelicaSystem does not Load Libraries before Model

[jules-l-jimmy]

On the latest OMPython, when using ModelicaSystem class with custom packages installed in custom directory and loading a model inside these packages, I have an error due to the fact that ModelicaSystem init loads the file and then the library.

To solve this, I exchanged the loadFile and loadLibrary in the __init__.py file line 862

Now it looks like this

        if fileName is not None:
            self.loadLibrary(verbose)
            self.loadFile(verbose)
