As a developer of a machine learning system, I want to request the server filters out entries as a download option so that my local data set is less biased.

Acceptance Test:

1. Upload a data set with a correlation between rainy street photos and sunny park photos.
2. Download the dataset with a box ticked for the filter
3. Verify that the filtered dataset contains at least 90% of the original data set
4. Verify that the correlation between rain and streets is weaker than the original dataset
5. Verify that the correlation between sun and parks is weaker than the original dataset
6. Repeat this process with each category of weather and daylight levels.
