mask and mask-colmap #63

Thanks a lot for sharing the code! I noticed that there are mask and mask colmap folders in the dataset you shared, but I could not generate these two folders by using the "Nerfies Capture Processing v2. ipynb" you provided, which made it impossible for me to carry out my own training in the next step. Could you please tell me how to generate the contents of these two folders? Thank you very much.
