Temporal issues in mozart-pianosonatas partition (example: mozart-piano-sonatas_27.jams)

[andreamust]

The mozart-piano-sonatas partition contains errors in the encoding of temporal information within its chord annotations. Below is an excerpt from mozart-piano-sonatas_27.jams:

"namespace": "chord_roman",
      "data": [
        {
          "time": 1.1,
          "duration": 2.0,
          "value": "C:I",
          "confidence": 1.0
        },
        {
          "time": 3.25,
          "duration": 0.5,
          "value": "C:viio64",
          "confidence": 1.0
        },
        {
          "time": 4.1,
          "duration": 2.0,
          "value": "C:I",
          "confidence": 1.0
        },
        {
          "time": 5.1,
          "duration": 2.0,
          "value": "C:IV",
          "confidence": 1.0
        },
        {
          "time": 6.1,
          "duration": 2.0,
          "value": "C:I",
          "confidence": 1.0
        },
        {
          "time": 7.1,
          "duration": 1.0,
          "value": "C:V(64)",
          "confidence": 1.0
        },

These entries exhibit non-monotonic time values, overlapping intervals, and inconsistent durations, which may lead to ambiguity in downstream processing.
