Duplicate category id with the same name

[lamblin]

In the available annotations for both "train" and "val", 4 categories have non-unique names:

• "id": 186 and "id": 1333 both have "name": "Cortinarius anomalus"
• "id": 543 and "id": 1334 both have "name": "Inocybe rimosa"

I don't know if an updated version of the dataset is planned, but it might also be useful for anyone using this dataset after the competition.
