Demo Files/Documentation.

[mizdflop]

I'm interested in trying out the library and trying to walk through the demo. There's no documentation as mentioned in pLitter/demo/pLitterStreet_demo.ipynb: "A video file and GPS track file in CSV format is must. Check out the documentation for preparing it." And I can't seem to download the sample data from the google drive. I think it has been removed. Thanks.

@mizdflop I Updated a temporary drive link for now, tested in colab and it is working, please check updated pLitter/demo/pLitterStreet_demo.ipynb. Documentation is not managed in the repo. I will close the issue then after updating permanent link and adding the document sooner. Thanks.
