Split out small objects (candles)

[robmarkcole]

As raised by Farid on Icevision forum, small objects are detected with significantly lower accuracy. The Fire dataset does include many small objects in the form of candle flames, which are not really the kind of significant fires I wish to detect. Overall model accuracy could be improved by moving the candle images to a separate dataset.

Actually better to optimise model to detect small fires, since this is how all fires start!
