Description

Describe the problem

The train_extra split is not parsed by fiftyone. Looking at fiftyone/utils/cityscapes.py there seems to be no handling for this split.

Code to reproduce issue

fiftyone zoo datasets load cityscapes -k source_dir=.

With PWD having: gtCoarse.zip gtFine_trainvaltest.zip leftImg8bit_trainextra.zip leftImg8bit_trainvaltest.zip

Direção de pesquisa
Examine `fiftyone/utils/cityscapes.py` to find where splits like `train`, `val`, `test` are handled. Add similar logic for the `train extra` split, which is currently missing. The fix should parse `leftImg8bit trainextra.zip` and `gtCoarse.zip` accordingly. Review existing split parsing for patterns to replicate.
