Detailed data for powerImportBreakdown and powerExportBreakdown

[fcalderan]

The /power-breakdown/latest?zone=XX endpoint returns these sub-objects as a part of the response:

    ...
   "powerImportBreakdown": {
        "FR": 3050,
        "GR": 205
    },
    "powerExportBreakdown": {
        "FR": 0,
        "GR": 0
    },
    ...

Could it be feasible to have a breakdown of these values by source, both for import and export?

E.g.

    ...
   "powerImportBreakdown": {
        "FR": {
            "power": 3050,
            "sourcesBreakdown": {
              "gas": 439",
              "nuclear": 2500,
              "geothermal": 111
            }
        }
        "GR": {
            "power": 205,
            "sourcesBreakdown": {
              ...
            }
  
       }  
    },

In case of value equals to 0 the object could simply be

    "powerExportBreakdown": {
        "FR":  {
            "power": 0,
            "sourcesBreakdown": { }
       }
    },

app.electricitymaps.com already shows import and export of electricity between countries with the carbon intensity, so I suppose this data is somewhat available.

Thanks.
