fix repetition 'sunglasses' label

[darkasevgen]

There was a repetition "sunglasses" at IMAGENET_CLASSES.
As far as I understand, these class names have already been corrected (for instance, 'crane' transform into "crane bird" and "construction crane", but "sunglasses" haven't been).
Reference: https://www.kaggle.com/c/imagenet-object-localization-challenge/data?select=LOC_synset_mapping.txt

The desired mapping {folder name: class name}:
n04355933 sunglass
n04356056 sunglasses, dark glasses, shades

I have added this difference so that there are 1000 unique labels.

[EIFY]

There is another repeated label: "missile". According to huggingface the 2nd one has been changed to "projectile, missile".
