Repository: Unbabel/COMET
Issue: Show individual system scores in compare
Root cause: Unimplemented Feature Gap

## 🚀 Feature
When running `comet-compare` show the actual COMET score for each system. Is this possible?

### Motivation
I usually run the compare to know if a system is the best, statistically significant, but also want the COMET scores for each system.

### Alternatives
Show the COMET score for each system

### Additional context
Right now I have to run the test twice, one with `comet-score` and another one with `comet-compare`.
```
comet-score --quiet data/fren/wmt14.en -r data/fren/wmt14.en -t hyps/wmt14.base-*.en
```
```
hyps/wmt14.base-bergamot.en     score: 0.7531
hyps/wmt14.base-wmt-opus.en     score: 0.7234
hyps/wmt14.base-wmt.en  score: 0.7055
```

```
comet-compare -s data/fren/wmt14.en -r data/fren/wmt14.en -t hyps/wmt14.base-*.en
```
```
