[0.17.18] raw-fish doesn't show in item_production_statistics.input_counts

[Discordia23]

This is a very minor issue of production API consistency.

After catching fish, game.player.force.item_production_statistics.input_counts DOES NOT contain an entry for 'raw-fish'

After consuming fish, game.player.force.item_production_statistics.output_counts DOES contain an entry for 'raw-fish'

While not scenario specific, this affects PVP production battles such that caught and consumed fish count negatively towards score.

Fish will show up under the "Buildings" tab since they're counted as in-world things you mine - like rocks/resources.
