Harvest ideas from global-wheat-detection

[robmarkcole]

https://www.kaggle.com/c/global-wheat-detection has a custom parser in IceData so likely some good notebooks to learn from.

See https://github.com/lgvaz/mantisshrimp/blob/master/notebooks/custom_parser.ipynb which is also https://airctic.com/custom_parser/ and used in https://www.kaggle.com/quazar/fasterrcnn-mantisshrimp-starter
