test_synthesizer_mp.py crashes after completing MP synthesizer computation

[wesmwoo]

Thank you for sharing this very cool project!

I have been trying to run test_synthesizer_mp.py on my local machine. After a couple days of computation, the MP synthesizer finally finished. However, in the "Generating Operational Satellite Data" step, it seems a syntax error has caused the test program to crash before saving the results of the MP synthesizer.

Below is the output:

I was able to patch this locally by adding texture_save_path as a function parameter in generate_operation_sat_location and changing replacing self.texture_save_path.
