Duplicated note in MIDI annotation

Hi first, thanks for this dataset.

After parsing the `.jams` files I've noticed that in the `02_Funk2-119-G_comp.jams` of the [version 1.1.0](https://zenodo.org/record/3371780) of the dataset, there is a duplicated note:

```
{'time': 10.860365532879541, 'duration': 0.243809523809432, 'value': 50.063616568428756, 'confidence': None}
{'time': 10.860546938775315, 'duration': 0.06965986394561696, 'value': 50.08643818571459, 'confidence': None}
```

Locate 02_Funk2-119-G_comp.jams in the version 1.1.0 dataset and inspect the two annotation entries at approximately 10.86 seconds. Confirm whether they represent a duplicate note, then update the annotation so the reported duplication is resolved. No test or repository path is mentioned; done means the affected annotation no longer contains the erroneous duplicate.
