Determine appropriate datasets/contrasts for analysis

[tsalo]

I assume we will want to analyze the same contrast across as many Neuroscout datasets as possible, so the key question is which features we want to use. Here's are a few that look like reasonable targets:

• face_detectionConfidence (GoogleVisionAPIFaceExtractor)
• shot_change (GoogleVideoAPIShotDetectionExtractor)
• people (ClarifaiAPIImageExtractor)
• face (ClarifaiAPIImageExtractor)
• as-Speech (AudiosetLabelExtractor)
• button_press (events)
