Suggestions to improve clarity of tutorial

[PatBall1]

• check for missing function calls - project_to_geojson, stitch_crowns, clean_crowns
• clarify how to connect with personal google drive
• clarify Confidence_scores and how filtering should be applied as a post-processing step
• note to avoid redownloading models as this impacts bandwidth
• add illustrations of training data, outputs etc
• explain the early stopping mechanism in more detail

Could you add an example for how to input a .png file then get the output based on the pre-trained model.
