Version CodiESP benchmark dataset

this includes original dataset and its translations and labels that might get refined in the future. Use DVC. The codiESP benchmark data directories should have these dirs:
- `benchmark / codiesp / english / test `
- `benchmark / codiesp / english / train `
- `benchmark / codiesp / spanish / test `
- `benchmark / codiesp / spanish / train `

git add benchmark/codiesp/english/test.dvc
git commit -m "Track translated English codiESP test reports”
dvc add benchmark/codiesp/spanish/train/
git add benchmark/codiesp/spanish/train.dvc
